Poly[bis-(p-toluene sulphonate) of 2,4-hexadiyne-1,6-diol] Langmuir-Blodgett thin film formation and characterization

摘要

Coherent thin films of bis-(p-toluene sulphonate) of 2,4-hexadiyne-1,6-diol (TS) and its polymer, PTS, were prepared by the Langmuir-Blodgett method. Even though TS has no amphiphilic groups at each end, it has an isotherm curve similar to stearic acid and can be transferred to a flat solid substrate under a certain pressure. Polarized UV-Vis spectroscopy, atomic force microscopy (AFM) and scanning electron microscopy (SEM) were used to characterize this kind of LB thin film's anisotropy, surface morphology, and topography.
