Properties and Applications of Alkylsiloxane-Modified UV-Embossed Holographic Plastics
摘要
Abstract
UV embossed holographic plastics are optical functional materials fabricated via UV-curing technology,enabling the transfer of microscale and even nanoscale structures from a nickel master to flexible substrates.Compared to thermal molding,UV molding proceeds at room temperature without high pressure,allowing deeper pattern replication.However,strong adhesion to the nickel master often causes sticking,leading to defects.Herein,we modified the UV resin with dodecyltrimethoxysilane(DTMS).Results show that it reduces viscosity by 38%and surface energy by 44%at 7%DTMS,significantly lowering the highest shed area ratio from 93%to 11%and the sticking frequency from 100%to 13%in 15 tests,while maintaining a final monomer conversion of 99%.The modified holographic plastic exhibits good UV aging resistance(ΔE＜2 after 168 h).Also,it enables accurate reproduction of complex optical effects,such as a 3D image to the naked eye and an in-situ integrated quad-image.关键词
