LOW REFRACTIVE INDEX FLUOROPOLYMER COMPOSITIONS HAVING IMPROVED COATING AND DURABILITY PROPERTIES

摘要

LOW REFRACTIVE INDEX FLUOROPOLYNIER COMPOSITIONS HAVING IMPROVED COATINC AND DURABILITY PROPERTIFS A LOW REFRACTIVE INDEX COMPOSITION THAT FORMS A LOW REFRACTIVE INDEX LAYER ON AN OPTICAL DISPLAY IS FORMED HAVING A CO-CROSSLINKED INTERPENETRATING POLYINER NETWORK OF A FLLLOROPOLYINER PHASE AND AN ACRYLATE PHASE. THE FLUOROPOLYRNER PHASE IS PREFERABLY FORMED FROM FLUOROPOLYMERS BASED ON TIFV OR FKM AND HAVING EITHER A DEGREE OF UNSATURATION AND/OR CONTAINING A REACTIVE CURE SITE MONOMER IN ITS POLYMER BACKBONE. THE ACRYLATE PHASE INCLUDES A MULTIFUNCTIONAL ACRYLATE CROSSLINKER, AND MORE PREFERABLY INCLUDES A PERFLUOROPOLYETHER ACRYLATE CROSSLINKER. THE FORMED LOW REFRACTIVE INDEX LAYER HAS IMPROVED INTERFACIAL ADHESION TO OTHER LAVERS OR SUBSTRATES CONTAINED IN THE OPTICAL DISPLAY. FURTHER, THE MECHANICAL STRENGTH AND SCRATCH RESISTANCE OF THE EITHER OF ABOVE LOW REFRACTIVE INDEX COMPOSITIONS CAN BE FURTHER ENHANCED THROUGH THE INCORPORATION OF SURFACE FUNCTIONALIZED INORGANIC PARTICLE INTO THE FORMED LAYER.
