Case Study

Aminophenyltrimethoxysilane for the Preparation of Chemically Bonded Silica-Titania-Aramid Hybrid Films

Sarwar M.I., et al. European Polymer Journal, 2000, 36(1), 89-94.

Aminophenyltrimethoxysilane (APTMOS) was employed to achieve chemical bonding between aramid chains and inorganic networks in silica- and titania-containing hybrid materials. Aromatic polyamide was first synthesized by reacting m- and p-phenylene diamines with terephthaloyl chloride in anhydrous DMAC under controlled cooling and stirring conditions. For chemically bonded hybrids, aramid chains were end-capped with APTMOS via reaction with terminal carbonyl chloride groups. Subsequent co-hydrolysis and condensation of APTMOS with tetraethoxysilane (TEOS) or tetrapropylorthotitanate (TPOT) in DMAC formed silica or titania networks covalently linked to the polymer matrix. Thin, transparent films with up to 20 wt% metal oxides were obtained through solvent evaporation, followed by water soaking and vacuum drying. Dynamic mechanical thermal analysis revealed enhanced α-relaxation shifts in chemically bonded ceramers, demonstrating the superior interphase interaction imparted by APTMOS.
