A METHOD OF FORMING A VDF OLIGOMER OR CO-OLIGOMER FILM ON A SUBSTRATE AND AN ELECTRICAL DEVICE COMPRISING THE VDF OLIGOMER OR CO-OLIGOMER FILM ON THE SUBSTRATE

摘要

A method of forming a vinylidene fluoride (VDF) oligomer or co-oligomer film on a substrate is disclosed. The method comprises forming a VDF oligomer or co-oligomer precursor solution; depositing the VDF oligomer or co-oligomer precursor solution onto the substrate to form a preliminary VDF oligomer or co-oligomer film on the substrate; and applying uniaxial pressure on the preliminary VDF oligomer or co-oligomer film and the substrate at an elevated temperature to form the VDF oligomer or co-oligomer film on the substrate. The substrate may comprise a metal surface which may be used as a bottom electrode and a top electrode may be deposited on the VDF oligomer or co- oligomer film. The VDF oligomer or co-oligomer film, the bottom electrode on the substrate and the top electrode on the VDF oligomer or co-oligomer film form an electrical device.
