| dc.description.abstract | In this research, hydroxyl terminated polysiloxane [poly(dimethylsiloxane)] was synthesized from dichlorodimethylsiloxane and it is incorporated into diglycidylether bisphenol A (DGEBA) epoxy resin to give a three-dimensional cross-link network. However, highly cross-linked DGEBA epoxy resins are organic materials which are relatively brittle and exhibits higher glass transition temperature. Thus, inorganic poly(dimethylsiloxane) (Si-O bond) is incorporated due to its many unique properties, such as low glass transition temperature, low surface tension, good flexibility, non-flammability and high resistance to thermal oxidation. Ccured blends of SG/DGEBA were studied by Hardness test, FTIR and DSC in this research. It was found that FTIR had proven the presence of poly(dimethylsiloxane)-co- DGEBA at which the important peaks had shown the presence of respective chemical bonds. Poly(dimethylsiloxane)-co-DGEBA obtained by using synthesized hydroxy- terminated poly(dimethylsiloxane) shown greater glass transition temperature and hardness compare to the one synthesized by using Aldrich hydroxy-terminated poly(dimethylsiloxane). The difference was due to less viscous and lower molecular weight of supply hydroxy-terminated poly(dimethylsiloxane) compare to synthesized hydroxy- terminated poly(dimethlysiloxane). | |
