In this work, plasma and surface coating technologies were combined and used in the modification of room-temperature-vulcanisated silicone rubber (RTV), and their properties were characterised and compared. First, the surface of pure RTV was cured by different plasmas to improve its roughness and hydrophilicity. The plasmas used was nitrogen, oxygen, and atmosphere plasmas. Then, a type of silicone coating, SC, was sprayed on the surface of this plasma treated RTV, and different RTV composites were prepared. The thermal dimensional stability, tensile properties, thermal stability, and acid and alkali resistance of these RTV composites were measured. Results showed the thermal dimensional stability parameters, COLE and COVE, of RTV/SC/P–O₂ were much lower compared to neat RTV. Meantime, their tensile properties together with acid and alkali resistance were improved. However, their initial thermal stability was decreased. These RTV composites were also characterised by contact angle test, scanning electron microscope observation, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy.

通过等离子和表面涂层技术固化的RTV模具橡胶

在这项工作中，将等离子和表面涂层技术相结合并用于室温硫化硅橡胶（RTV）的改性，并对其性能进行了表征和比较。首先，通过不同的等离子体固化纯RTV的表面，以提高其粗糙度和亲水性。使用的等离子体是氮气，氧气和大气等离子体。然后，在这种经过等离子体处理的RTV的表面上喷涂一种有机硅涂层SC，从而制备了不同的RTV复合材料。测量了这些RTV复合材料的热尺寸稳定性，拉伸性能，热稳定性以及耐酸碱性能。结果显示RTV / SC / P–O ₂的热尺寸稳定性参数COLE和COVE与纯净的RTV相比要低得多。同时，它们的拉伸性能以及耐酸和耐碱性得到了改善。但是，它们的初始热稳定性降低了。这些RTV复合材料还通过接触角测试，扫描电子显微镜观察，傅里叶变换红外光谱和X射线光电子能谱进行了表征。
