Janus颗粒的制备及泡沫性能
Preparation and Foam Properties of Janus Particles
摘要
Abstract
The monodisperse silica nanoparticles were synthesized, and then amphiphilic Janus particles decorated with fluorinated chains were prepared by improving Pickering emulsions method. The self-assembly behavior at the air-water interface and foam properties of Janus particles were investigated.The size distribution of silica nanoparticles,surface morphology of wax colloidosomes and chemical composition,surface structure, interfacial activity, foam properties of Janus particles were characterized by particle size analyzer, scanning electron microscopy(SEM),Fourier transform infrared spectroscope(FTIR), fluorescence microscope, inter-facial rheometer and foamscan. The results show that the surface of the prepared Janus particles is asymmetric. The test results of interfacial activity show that Janus particles have favorable interfacial activity at the gas/liquid interface,and the surface tension could be reduced to 38 mN/m. The test results of foam properties show that Janus particles effectively controll the coalescence and disproportionation, and the foam shows excellent stability.关键词
