| Abstract: | Barium titanate (BaTiO3)/polymer composite was successfully synthesized by methacryltriisopropoxytitanium (MTPT) and barium alkoxide. MTPT undergoes radical polymerization using azobisisobutyronitrile at temperatures from 90 to 150°C. 1H NMR spectra showed that MTPT reacted with barium alkoxides yielding a complex alkoxide. BaTiO3 particles/polymer was formed after the polymerization and hydrolysis of the complex alkoxide. The transmission electron microscopic observation revealed that crystalline BaTiO3 particles of around 3 nm in size were dispersed in the polymer matrix. |
