Nowadays, there is a need for a paradigm shift in material selection for surface coatings so as to meet the requirements of advanced systems. Polyhedral oligomeric silsesquioxanes (POSS) are three-dimensional networks with a silica-like core covered by an organic shell, a promising nanosized structure for organic coatings. The use of POSS structures in coating materials has experienced an almost erratic period over the past decade, mainly because of the synthesis of POSS being exclusive and, to some extent, expressive. However, there has been a big return to the use of POSS in coatings during the last years. Epoxy is best known for its versatility of usage as an organic coating. Hybrid organic–inorganic POSS nanostructures with unique properties are a complement to the epoxy for coating applications. The tailorable compatibility and considerable reactivity of POSS molecules towards organic groups have made them promising candidates for emerging multifunctional epoxy coatings. In this sense, the focus of this review is placed on POSS/epoxy nanocomposite coatings. The thermal, mechanical, anti-corrosion and dielectric properties of POSS/epoxy coatings have been comprehensively studied and discussed.

多面体低聚倍半硅氧烷/环氧涂料：综述

如今，需要对表面涂层的材料选择进行范式转换，以满足先进系统的要求。多面体低聚倍半硅氧烷（POSS）是三维网络，其二氧化硅样核心被有机壳覆盖，这是一种有前途的有机涂料纳米结构。在过去的十年中，在涂层材料中使用POSS结构经历了近乎不稳定的时期，这主要是因为POSS的合成是排他性的，并且在某种程度上是表达性的。但是，最近几年，在涂料中使用POSS的回报很大。环氧树脂以其用作有机涂料的多功能性而闻名。具有独特性能的有机-无机POSS杂化纳米结构是环氧涂料的补充。POSS分子对有机基团的可定制的相容性和可观的反应性使其成为新兴的多功能环氧涂料的有希望的候选者。从这个意义上讲，本综述的重点放在POSS /环氧纳米复合涂料上。对POSS /环氧树脂涂料的热，机械，防腐和介电性能进行了全面的研究和讨论。
