Mechanism of superior thermal insulation of nano-sized hollow/polymer hybrid thin film

在本研究中，我们重点解释了纳米中空/聚合物杂化薄膜优越的隔热性能。这种隔热性能可以从中空二氧化硅纳米颗粒的壳层结构中得到。为了设计壳的微观结构，对壳的形成条件进行了优化。结果表明，在分子水平上控制壳层微观结构可以提高复合膜的隔热性能。此外，还调整了空心颗粒表面与聚合物的界面，使聚合物基体中颗粒浓度较高。

In this study, we focused on explanation of superior thermal insulation property of nano-hollow/polymer hybrid thin film. The thermal insulation could be derived from shell microstructure of the hollow silica nanoparticles. In order to design the shell microstructure, shell formation condition has been optimized. As a result, it can be clear that control of shell microstructure on a molecular level improved thermal insulation property of the composite film. In addition, interface between hollow particle surface and polymer has been adjusted to obtain high particle concentration in polymer matrix.
