Abstract

A new type of dual-functional optically clear adhesive (OCA) with UV protection and wide viewing capabilities was fabricated using TiO₂ nanoparticles. UV-visible spectroscopy was used to determine the transmittances of OCA films, and a laser oscilloscope and a bar-type LED lamp were used for light-diffusion studies. Modified TiO₂ nanoparticles with core-shell structures have different refractive indices to the unmodified particles and exhibit improved UV protection and light-scattering abilities. Therefore, dual-functional OCAs, rather than normal OCAs, help to protect light-emitting modules or the naked eye, and images emitted from such modules are observed more clearly from a variety of angles.

摘要

_{使用TiO 2}纳米粒子制备了一种新型的具有防紫外线和宽视野能力的双功能光学透明粘合剂（OCA） 。紫外-可见光谱用于确定 OCA 薄膜的透射率，激光示波器和条形 LED 灯用于光扩散研究。具有核壳结构的改性TiO _{2纳米粒子具有与未改性粒子不同的折射率，并表现出改进的紫外线防护和光散射能力。}因此，与普通的OCA相比，双功能OCA有助于保护发光模块或肉眼，并且从各种角度更清楚地观察到从此类模块发出的图像。
