OPTICAL QUALITY PVDF HAVING ENHANCED PIEZOELECTRIC RESPONSE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240084121 titled 'OPTICAL QUALITY PVDF HAVING ENHANCED PIEZOELECTRIC RESPONSE

Simplified Explanation

A mechanically and piezoelectrically anisotropic polymer article is formed from a crystallizable fluoropolymer and a nucleating agent. The polymer article may be a thin film or a fiber, for example. A crystalline phase may constitute at least approximately 50% of the polymer article. In certain examples, a fluoropolymer may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. The polymer article may include up to approximately 10 wt. % of the nucleating agent. Such a polymer article is optically transparent, has an elastic modulus of at least approximately 3 GPa, and an electromechanical coupling factor (k) of at least approximately 0.15.
