Organotin piezo- and pyroelectric polymer films. [Synthesis, glass transition, and piezo- and pyroelectric activity]
The synthesis of a new class of piezo- and pyroelectrically active materials of various co- and terpolymers of tributylin methacrylate (TBTM) and trimethyltin methacrylate (TMTM) is described. A description of sample preparation, poling techniques, and measurement system is given in some detail. Films of the various polymer compositions were evaluated for tin current, glass transition temperature (Tg), crystallinity or ordering of the amorphous phase and piezo- and pytoelectric activity. Experimental results on 25 to 30 mol% TBTM/methyl methacrylate copolymers, which possessed good piezoelectric activity, antifouling properties and paint-formulation characteristics, are discussed in detail. Solvent-induced orientation effects that lead to piezoelectric activity in amorphous, unpoled, polymers are also described.
