Micro Morphology

In this paper, a composite micromachining process is introduced. By adjusting the surface microstructure, a composite coating with two kinds of materials with different characteristics was fabricated. Carbon steel is used as the substrate material, and laser processing is used to obtain the micro morphology on the substrate surface. nanoSiC particles were selected as one of the coating materials, and the SiC coating was added through the process of micropore induced nanoparticles self-assembly. Ni was selected as another coating material and added by electrodeposition. This processing method can be used to prepare multifunctional surface coating, combining the characteristics of different materials. This work can provide an idea to create more excellent multifunctional surfaces.

Abstract A series of fluorinated-siloxane protective surface coating materials (FPA/SiO2) were prepared with different contents of dodecafluoroheptyl methacrylate (DFMA) and fixed content of siloxane. The properties of FPA/SiO2 protective materials were investigated by the methods of Fourier transform infrared spectroscopy (FT-IR) spectra, UV-Vis spectrum, transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The surface morphology and mineralogical analysis of the fresh and weathered stone samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The artificial ageing test, which was commonly used as a criterion for the evaluation of the protective ability of FPA/SiO2 coating material, was performed. The results indicate that when the content of DFMA is 30 wt.% and the content of SiO2 is 10 wt.%, the prepared coating material has good comprehensive performances. The artificial ageing test shows that the protective surface coating material has good compatibility with and similar appearance to stone relics. The effect of FPA/SiO2 protective coating material for protection of Jiaoshan Steles Grove (China) is noticeable and it can be widely applied to the protection of stone relics.

Forward osmosis (FO) is considered as one of the emerging techniques in membrane technology. The enhancement of FO performance is governed by two major factors: the first one is development of high-performance draw solutions and the second is utilizing of high efficient FO membranes. The aim of this work is to investigate chemical surface coating modification of commercial nonwoven forward osmosis membrane with new hydrophilic coating materials namely, o-phenylene di-amine and benzoyl chloride. The effect of coating addition at different concentrations was studied. The membrane morphology and chemical structure characterization of modified membranes proved the formation of dense layer and higher membrane porosity. Finally, it was demonstrated that increasing of coating material concentration gradually increases porosity and membrane performance till 0.75 g/l. By further increasing of coating materials, the porosity and membrane performance tend to decrease.
