摘要: Piezoelectric properties of polymeric substances arise from either the poling-induced orientation molecular dipoles (class 1) or uniaxial chiral chain molecules 2). The class 1 polymers include ferroelectric polymers, polar with frozen-in dipole orientation, and composites ceramics. Details poling procedure in representative materials are described, optimum conditions suggested. Resulting piezoelectric pyroelectric activities specified as a function remnant polarization, underlying basic mechanisms summarized. 2 consist drawn optically active exhibit face-shear piezoelectricity appearing proportion to coefficient axes. spontaneous polarization liquid-crystalline is attributable this type coupled strain. >
