采用低压等离子体聚合技术,通过调整工作气压和反式二丁烯(T2B)与H2流量比制备了辉光放电聚合物(GDP)涂层.利用傅里叶变换红外吸收光谱和元素分析法讨论了工作气压和T2B与H2流量比对GDP涂层内部H原子含量及结构的影响,并且通过纳米压痕技术对GDP涂层的硬度及杨氏模量进行了表征.研究结果表明:降低工作气压和T2B与H2流量比,GDP涂层内sp3CH3基团与H原子含量随之逐渐降低,sp2CH2基团、sp3CH2基团和sp3CH基团含量随之增加,涂层的网络结构交联化程度增强,硬度和杨氏模量增大.
Glow discharge polymer (GDP) coatings were prepared by low-pressure plasma polymerization with the adjustment of operating pressure and the flow ratio of trans-dibutylene (T2B) to H2. The Fourier transform infrared spectroscopy and elemental analysis The influence of operating pressure and T2B to H2 flow ratio on the content and structure of H atom in GDP coating was investigated, and the hardness and Young’s modulus of GDP coating were characterized by nanoindentation technology.The results show that: And T2B and H2 flux ratio, GDP coating sp3CH3 group and H atom content decreased, sp2CH2 group, sp3CH2 group and sp3CH group content increased, the degree of crosslinking of the network structure of the coating increased, Hardness and Young’s modulus increase.
