Synthesis and characterization of the PMMA/ Sio2 hybrids by sol-gel method

Abstract

This research describes the synthesis and  characterization of the organic –inorganic hybrid materials( (methyl methacrylate) (PMMA) and tetraethyl orthosilicate (TEOS))  film were fabricated using sol-gel technique T₁=20/80,T₂=50/50,T₃=80/20. the ratios of PMMA/TEOS   (20\80,50/50,80/20) V/V,  .The  films were then  characterized using  FTIR, TGA ,and UV-VIS., the hybrids organic –inorganic film is devised by the assembly between silica xerogel and polymer with C=O group via hydrogen bonding  .The best  transmission of the ratio PMMA/TEOS  is ( 80/20),the thermal gravimetric analysis the  stable thermal with increasing PMMA content   .
