笼型聚倍半硅氧烷POSS添加剂在能量固化涂料中的应用技术综述

摘要

笼型聚倍半硅氧烷即多面体低聚倍半硅氧烷（POSS®）添加剂提供了一种简单易用的化学工具包，只需少量负载即可改善传统配方。在1.5-3.0nm的直径下，POSS笼在结合到制剂中时提供了巨大的表面积和体积控制。POSS添加剂赋予光学涂层附着力、硬度和耐刮擦性能。它们还提高了紫外光固化的程度和速率，部分原因是它们的表面积和高度的功能化。将讨论丙烯酸和环氧POSS的基本属性，以及解释能量固化涂料配方中观察到效果的相关材料科学模型。

Abstract

Polyhedral oligomeric silsesquioxane (POSS®) additives provide a simple-to-use chemical tool kit that that requires only small loading levels to improve traditional formulations. At 1.5-3.0 nm in diameter, POSS cages provide a tremendous amount of surface area and volume control when incorporated into formulations. POSS additives impart adhesion, hardness, and scratch resistance properties in optical coatings. They also improve the degree and rate of ultraviolet light cure due in part to their surface area and high degree of functionalization. The fundamental attributes of acrylic and epoxy POSS will be discussed as well as the related material science models that explain the observed effects in energy-cure coating formulations.
