Abstract

In this study, surface modification of basalt fibers (BFs) utilizing atmospheric pressure plasma deposition was carried out. Using this one-step deposition approach, three siloxane precursors with different structures including methyltrimethoxysilane (MTMS), hexamethyldisiloxane (HMDSO), and tetramethoxysilane (TMOS) were deposited on BFs surface, respectively. The physicochemical properties of the thin films from three different siloxane compounds are elucidated. In comparison with MTMS-coated sample, HMDSO-coated and TMOS-coated BFs surfaces feature an improved thermal insulation performance. The results demonstrate that atmospheric pressure plasma deposition is an efficient approach to modify flexible materials surface with improved thermal insulation. Moreover, it provides a reference to decide which precursor type is preferred for certain applications.

使用不同硅氧烷前体的常压等离子体在玄武岩纤维表面沉积薄膜

本研究利用常压等离子沉积法对玄武岩纤维（BF）进行了表面改性。利用这种一步沉积法，在玄武岩纤维表面分别沉积了三种不同结构的硅氧烷前体，包括甲基三甲氧基硅烷（MTMS）、六甲基二硅氧烷（HMDSO）和四甲氧基硅烷（TMOS）。研究阐明了三种不同硅氧烷化合物薄膜的物理化学特性。与 MTMS 涂层样品相比，HMDSO 涂层和 TMOS 涂层 BFs 表面具有更好的隔热性能。研究结果表明，常压等离子沉积是一种有效的方法，可以改善柔性材料表面的隔热性能。此外，它还为决定在某些应用中选择哪种前驱体类型提供了参考。
