TL;DR: In this paper, a texture piezoelectric polymer film of high transverse effect and a preparation method of the film is presented. But the texture is not textured.
Abstract: The invention discloses a texture piezoelectric polymer film of high transverse effect and a preparation method of the film. The nonisothermal crystallisation process of the film prepared by the solution method is controlled to realize preferable orientation of molecular dipole moment of the film is realized, and the piezoelectric polymer film of the texture structure in which the molecular dipoles are arranged preferably along the plane of the film is prepared. The piezoelectric polymer film is characterized in that the horizontal piezoelectric effect of the film is higher than that of a film of the same components but without texturizing, can be applied to preparation of a sensor of high transverse piezoelectric effect, and has good application prospects in the fields of a flexible nano generation system and a novel energy collection system.

TL;DR: In this article, a simple preparation method for a nanometer rod or nanometer wire of a piezoelectric polymer P(VDF-TrFE) is presented.
Abstract: The invention discloses a simple preparation method for a nanometer rod or nanometer wire of a piezoelectric polymer P(VDF-TrFE). The nanometer rod or nanometer wire of the polymer is prepared by combining the dewetting effect of a substrate with the diffusion limitation effect of a film in the nonisothermal crystallization process on the basis that the film of the piezoelectric polymer is prepared by a solution method. According to the preparation method, needed devices are simple, operation is convenient, and the prepared nanometer rod or nanometer wire of the polymer is high in the degree of crystallization and good in the piezoelectric effect, can grow in specific direction, and can be applied to related piezoelectric type sensors, flexible nanometer power generation systems and the like.

Abstract: The ability to create arbitrary patterned linear and circular infrared (IR) liquid crystal polymer (LCP) polarizers is demonstrated. The operating wavelength of the thin-film polarizer ranges from 700 to 4200 nm. The linear micropolarizer is fabricated using IR dichroic dye as a guest in LCP host with feature size as small as 4 μm. The circular micropolarizer is fabricated using cholesteric LCPs with feature size as small as 6.2 μm.
