Abstract
Transparent nanocomposite films based on a thermoplastic elastomer, poly[styrene-b-(ethylene-co-butylene)-bstyrene] triblock copolymer (SEBS), and titania sol-gel precursors are fabricated. The SEBS grafted with maleic anhydride (SEBS-g-MAH) can enhance the dispersion of titania in the SEBS matrix. The SEBS-g-MAH/titania nanocomposite films are transparent and exhibit excellent mechanical properties, including increased modulus and tensile strength, with only a slight loss of stretchability. Moreover, the uniformly dispersed titania nanoparticles in the SEBS-g-MAH matrix can enhance thermal stability of the nanocomposites. 34 Refs.
