用射频磁控溅射方法分别在NaCl和Si基底上制备了聚四氟乙烯薄膜.通过红外吸收光谱的研究分析了薄膜中的成分及分子链结构.Polytetrafluoroethylene (PTFE) thin films have been grown successfully by rf magnetron sputtering technique. The infrared spectra of the as prepared films are consistent with those of the PTFE target. However, chains in the films become shorter than those in the bulk.
