Effect of heat treatment on morphology and polymerization of Langmuir-Blodgett films of amphiphilic diacetylene complexed with polyallylamine
Langmuir-Blodgett (LB) films of an amphiphilic diacetylene (DA) complexed with polyallyamine (PAA) were fabricated. Textural structures were observed in the AFM images, while the surface was covered with small grains after the heat treatment at temperatures higher than 100 degreesC. The polymerization of DA proceeded by the irradiation with UV light before the heat treatment whereas only a small fraction of DA polymerized after the heat treatment. The LB films of polymerized DA complexed with PAA showed better stability against heat treatment than the ones without PAA.
