- Abstract
Hybrid materials of inorganic-organic phases in which each phase provides different functionality are attractive candidates for achieving multifunctionality. Using a layer-by-layer approach, we fabricated sheets of piezoelectric polymer P(VDF-TrFE) reinforced by aligned sub-micron thick sapphire platelets. The films were transparent and piezoelectric, exhibited ductility up to ≈330%, and tensile toughness of up to 26 J g-1. We investigated the effect of thermal annealing on the crystallinity of the polymer phase and its effect on the mechanical and piezoelectric properties of the films. Thermal annealing resulted in improvement of the elastic modulus and piezoelectric properties of the films. in situ SEM tensile experiments were conducted for observation of the deformation mechanism of the films.
