POLYFLUORENE-BASED POLYMER-POLYVINYLIDENE FLUORIDE GRAFT COPOLYMER AND ELEMENT INCLUDING THE SAME

摘要

Disclosed is a graft copolymer containing a polyfluorene-based polymer as a main chain and a polyvinylidene fluoride (PVDF) as a side chain, and an element including the same. The graft copolymer contains both the polyfluorene-based polymer and the PVDF, so that the graft copolymer may increase miscibility between polymers to prepare a composite having excellent performance, prepare an uniform thin film through a solution process, and be used as a single material that exhibits both piezoelectric properties and luminescence properties.
