Yoon-Seok Shin et al., Chem Sci J 2018, Volume 9 conferenceseries.com DOI: 10.4172/2150-3494-C3-024 International Conference on Materials and Polymer Chemistry July 05-06, 2018 Bangkok, Thailand Phosphorus-containing flame retardant in building applications with flame retardancy, thermal stability and processability Yoon-Seok Shin, Min-Ji Sim and Sang-Ho Cha Kyonggi University, South Korea B uilding materials consisted of combustible polymers are causing the spread of large-scale fire. Accordingly, many researches on flame retardant materials that can prevent the combustion of polymers have been conducted. So, we synthesized a Phosphorus-containing Flame Retardant (PFR) and prepared Flame Retarded Polylactide (FR-PLA) with different contents of PFR. Limiting Oxygen Index (LOI) and the vertical burning test (UL 94) were performed to evaluate the flame retardancy. The thermal degradation process was analyzed by TGA and real-time FTIR. With 3 wt.% loading of PFR, LOI increased from 23% to 30%. Then the maximum-thermal degradation temperature increased. Additionally, to investigate the mechanical property and melting behavior, UTM and DSC were conducted. As a result, we confirmed that PFR have flame retardancy, thermal stability and processability for PLA. Biography Yoon-Seok Shin is an Associate Professor of the Department of Architectural Engineering at Kyonggi University, South Korea. He is conducting research on construction industry such as execution of building works and building equipment. shinys@kgu.ac.kr Chemical Sciences Journal Chemistry 2018 Volume 9 July 05-06, 2018 Page 24

Chem Sci J 2018, Volume 9 conferenceseries.com DOI: 10.4172/2150-3494-C3-024 International Conference on Materials and Polymer Chemistry July 05-06, 2018 Bangkok, Thailand Effect of gamma irradiation on the mechanical properties of PVC/ZnO polymer nanocomposite Abdullah Faisal Al Naim King Faisal University, Saudi Arabia P olyvinyl Chloride (PVC) based nanocomposite with different weight ratios of Zinc oxide (ZnO) nanoparticles is prepared by using a gel-like technique. The weight-ratio of ZnO nanoparticles, in a range of 2.5 to 10 wt.%, is used to prepare nanocomposites in the Tetrahydrofuran (THF) solvent. The prepared samples are exposed to gamma (γ) radiation at different doses in a range of 5-40 kGy. The mechanical properties of irradiated samples are compared to that of un-irradiated samples. For un-irradiated samples, the elasticity is found to increase with the addition of ZnO nanoparticles. However, the plastic region of the stress-strain curve gets slightly affected on increasing the concentration of ZnO. Additionally, the elastic modulus is noticed to drop exponentially with ZnO concentration. For pure PVC, a slight dependence of stress-strain curves on the gamma irradiation doses has also been detected. Further, the gamma irradiation dose results in a detectable decrease of elastic modulus for pure and low weight-ratio ZnO nanoparticles. However, the irradiation dose does not have any effect on the elastic modulus for the 10 wt.%, which is the highest weight ratio used in this study. anaim2@kfu.edu.sa Chemical Sciences Journal Chemistry 2018 Volume 9 July 05-06, 2018 Page 26

The functionalization of cotton avoids facile degradation and damage by the environment, moisture, microorganisms, etc., and allows obtaining a desired material with applications such as medical, construction and textile. Electrostatic assembly better known as Layer-by-Layer (LbL) technique is an alternative option of cotton modification consisted in depositing nanolayers by the adsorption of charged polyelectrolytes on the surface for further immobilization of nanoparticles. LbL technique is attractive for cotton modification due to its simplicity and easy incorporation in just one coating at ambient conditions. Nanostructured materials have been investigated in the textile field because of their attractive characteristics and unique physicochemical properties. Recently, core-shell nanoparticles have been focused for the combination of a core and a shell made by different precursors and whose unique and useful functionalities are obtained depending on this interaction affording to expand their applications according to the shape, size and smart characteristics given by these core-shell nanostructures. In the present study, we have pretreated and modified cotton fibers using PDDA and PSS polymers in order to functionalize the surface with charged polyelectrolytes for further nanoparticles attaching by electrostatic interaction. Magnetite and Magnetic core-shell mesoporous suspension were prepared for coating the cotton fibers to compare and characterize the resulting material as a novel, innovative and promising product for different fields of application. dpatinor@unicartagena.edu.co Chemical Sciences Journal Chemistry 2018 Volume 9 July 05-06, 2018 Page 27

YF3 nanoparticles (NP) were added at 1%, 2% and 3% (w/w) to the conventional orthodontic composite resin (Transbond XT). The blended composite resin was labeled as NP1, NP2 and NP3, respectively according to w/w of NP’s. A total of 60 extracted human premolars were randomly allocated into four groups of 15 (n=15). Orthodontic brackets were bonded using the conventional (control) and experimental composite resin (NP1, NP2 and NP3). The adhesion strength of the composite resin was determined by a universal testing machine. The debonding sites were assessed and scored using Adhesive Remnant Index (ARI). The antibacterial effect of Yttrium Fluoride (YF3) nanoparticles against Streptococcus mutans was assessed by viable cell counting method. For the same, a total of 40 composite discs specimen were prepared using the control and experimental composite resin (n=10). The data was analyzed by One-way ANOVA and Tukey’s post hoc analysis. In all the tests, the significance level was determined to be 0.05. The highest adhesion strength values were found in control group (11.61±0.23) and lowest values with NP3 group (10.49±0.17). Significant difference was observed between control and experimental groups, NP2 and NP3 (P0.05). The highest colony forming units (CFU) were found in control group (75.85±1.15) and the least CFU was found with NP1 group (2.24±1.14). Significant difference in the mean CFU of the conventional and experimental composite groups was observed (P

Compared to conventional solid-state lighting device such as Organic Light-Emitting Diode (OLED), Light-emitting Electrochemical Cell (LECs) possess simple device architecture and a low cost, solution based scalable process makes LECs more impressive. Mainly LECs are two types, p-LECS and Ir-ITMCs. Polymer light-emitting electrochemical cells are tri- component blend containing emitting polymer, an ion-conducting polymer and an inorganic salt. Currently much research has been focused on cationic iridium complexes due to the phosphorescent, color tuning and an ionic nature of Ir-ITMCs. However, the source and expensive nature of iridium demands new emitters in LECs. Recently non-ionic small molecule light- emitting electrochemical cell containing the device structure as same as the p-LEC were reported by Tang, et al. The molecule which is an ionic apart from Ir-ITMCs has great attentions. We designed and synthesized an ionic organic small derivative in multi-step synthetic procedure for light-emitting electrochemical cells. A complete structural, photo physical, electrochemical and electroluminescent properties were investigated. The emissions color-tuning of compounds were covering blue and region achieved by applying the target compound in a LEC device. k.shanraj@gmail.com Chemical Sciences Journal Chemistry 2018 Volume 9 July 05-06, 2018 Page 29
