红外光谱研究十八胺、硬脂酸及氘代硬脂酸Langmuir-Blodgett膜相变行为
Infrared spectroscopy study on the phase behavior of the Langmuir-Blodgett films of octadecylamine,stearic acid and deuterated stearic acid
摘要
Abstract
11-monolayer LB films of octadecylamine,stearic acid and deuterated stearic acid were prepared,and the phase behaviors of the three kinds of LB films were investigated by variable-temperature FTIR transmission spectroscopy.It was found： the phase transition of the octadecylamine LB films undergoes in the long and low temperature range of 55-75 ℃,and the frequencies of the CH2 symmetric and anti-symmetric stretching move to high energy area successively;the obvious order-disorder transition of the alkyl chains in the stearic acid LB films proceeds in the narrow temperature range of 70-80 ℃,the CH2 stretching frequencies and intensity ratio of a（CH2） to s（CH2） changes notably;phase behavior of deuterated stearic acid LB films takes place between 65-75℃,especially in the temperature range of 65-70 ℃,the phase transition is remarkable.关键词
