Abstract

Polytetrafluoroethylene (PTFE) films are deposited in parallel and perpendicular magnetic fields (MF) by electron-enhanced vacuum deposition (EVD) and EVD + low-temperature plasma (LTP) methods. The structure, morphology, and nanomechanical properties of the films are studied by infrared spectroscopy (IRS), atomic force microscopy (AFM), and spectroscopic ellipsometry. The structure of the thicker films is closer to that of bulk PTFE than that of thin films. The films' crystallinity and surface roughness are higher than those deposited without MF. The birefringence of the refractive index (n) of the films deposited in the MF is inverse to the anisotropy of the n of the films deposited without MF. The hardness of the films is close to that of bulk PTFE.

电子辅助真空沉积PTFE在磁场中生长薄膜的结构和光学异常

采用电子增强真空沉积（EVD）和EVD +低温等离子体沉积（LTP）方法在平行和垂直磁场（MF）下沉积聚四氟乙烯（PTFE）薄膜。利用红外光谱（IRS）、原子力显微镜（AFM）和光谱椭偏仪研究了膜的结构、形貌和纳米力学性能。较厚薄膜的结构比薄膜更接近块状聚四氟乙烯。膜的结晶度和表面粗糙度均高于未经MF处理的膜。薄膜的双折射率(n)的双折射与薄膜的n的各向异性成反比。薄膜的硬度接近块状聚四氟乙烯。
