Scanning electron microscopy siloxane

Therefore, innovative layers composed of siloxane/cerium and deposited by atmospheric pressure plasma have been tested. In this study, HMDSO was atomised and introduced as a precursor in an atmospheric pressure DBD plasma. The hybrid coating was obtained by mixing liquid precursor and nanoparticles (HMDSO and nanoAlCeOs) before atomisation. The properties of these different coatings were studied by scanning electron microscopy (SEM) and interferometry measurements. Their corrosion resistance has been determined electrochemically and their self-healing properties have been demonstrated by a combination of electrochemical impedance spectroscopy (EIS) and a nanoscratch method. 

A novel nanocomposite membrane, poly dimethyl siloxane (PDMS)/Au was prepared for carbon dioxide/methane separation. Synthesis of stabilized nano particles is also reported. The nanoparticles were characterized by UV-visible spectroscopy and transmission electron microscopy (TEM). The hybrid membrane was characterized morphologically by scanning electron microscope (SEM) and the change in inter-segmental distance due to filler loading by wide angle X-ray diffraction patterns (WAXD). The gas transport properties were measured at different pressures and temperatures. The effects of filler loading on permselectivity, diffiisivity selectivity and solubility selectivity are reported for CO2/CH4 separation. Reverse selective phenomena of PDMS/Au nanocomposite membrane over the conventional PDMS membrane is explained based on sorption kinetics of CO2.
