Piezoelectric and ferroelectric properties of polyurea-5 thin films prepared by vapor deposition polymerization

Submicron films of aliphatic polyurea-5 were synthesized by vapor deposition polymerization. The structure of films depended on the partial pressure ratio of evaporated monomers. Excess of diamine monomer over diisocyanate monomer yielded lower crystalline structure, to be poled easier at low temper...
