聚苯乙炔单分子膜成膜特性研究

STUDY ON PROPERTIES OF POLY (PHENYLACETYLENE) MONOLAYER FILM

研究了聚苯乙炔单分子膜的成膜特性及其结构。结果表明，聚苯乙炔能在较大的表面压范围内形成稳定的单分子膜，并具有不可重复压缩性、表面压力的各向异性和松弛特性。ＴＥＭ照片显示，聚苯乙炔分子链在单分子膜中是有序排列的。转移比和ＸＰＳ研究证明，单分子膜向铝片的沉积是成功的。

The monolayer film of polyphenylacetylene (PPA) is firstly prepared by Langmuir Blodgett (LB) technique. The properties and the structure of this film are investigated. It is found that PPA monolayer has nonrecompressibility, anisotropism and relaxation of surface pressure. TEM photograph shows the orientation and arrangement of PPA molecular chains in the monolayer is regular. Transfer ratios confirm that the monolayer film can be successfully deposited on the hydrophilic aluminum sheet. XPS measurement proves that atom ratios of the monolayer are in agreement with the component of PPA molecular structure. PPA LB monolayer film can be applied to the separation functional photoconductor as a charge generation layer.
