Micro Morphology

Abstract Micro-morphology of the rubber compounds, such as polymer compatibility and carbon black distribution, is one of the most important parameters affecting compound performance. Transmission Electron Microscopy (TEM) technique enables us to examine this micro-morphology, but has many difficulties. It requires high skill for sample preparation, high cost and a long time. Atomic Force Microscopy (AFM) technique is a relatively easy way for detecting these images. Through TM-AFM (Tapping Mode Atomic Force Microscopy) technique, two different polymer domains were distinguished in the unfilled rubber blend (natural rubber/ synthetic rubber blend). In order to verify the images, analogue signal (voltage) histograms for those images were analyzed by Gaussian multi-peak analysis method. Filler morphology was also examined in the filled natural rubber and filled rubber blend compounds. Silica and carbon black showed different behavior in the rubber blend. Carbon black lies predominantly in the polybutadiene rubber domain whereas silica exists in the natural rubber domain.

In this work, a mechanically durable anticorrosion superhydrophobic coating is developed using a nanocomposite coating solution composed of silica nanoparticles and epoxy resin. The nanocomposite coating developed was tested for its superhydrophobic behavior using goniometry; surface morphology using scanning electron microscopy and atomic force microscopy; elemental composition using energy dispersive X-ray spectroscopy; corrosion resistance using atomic force microscopy; and potentiodynamic polarization measurements. The nanocomposite coating possesses hierarchical micro/nanostructures, according to the scanning electron microscopy images, and the presence of such structures was further confirmed by the atomic force microscopy images. The developed nanocomposite coating was found to be highly superhydrophobic as well as corrosion resistant, according to the results from static contact angle measurement and potentiodynamic polarization measurement, respectively. The abrasion resistance and mechanical durability of the nanocomposite coating were studied by abrasion tests, and the mechanical properties such as reduced modulus and Berkovich hardness were evaluated with the aid of nanoindentation tests.

Collagen films are widely used as adhesives in medicine and cosmetology. However, its properties require modification. In this work, the influence of salicin on the properties of collagen solution and films was studied. Collagen was extracted from silver carp skin. The rheological properties of collagen solutions with and without salicin were characterized by steady shear tests. Thin collagen films were prepared by solvent evaporation. The structure of films was researched using infrared spectroscopy. The surface properties of films were investigated using Atomic Force Microscopy (AFM). Mechanical properties were measured as well. It was found that the addition of salicin modified the roughness of collagen films and their mechanical and rheological properties. The above-mentioned parameters are very important in potential applications of collagen films containing salicin.

By using a solvent-based method composites of ethylenevinyl acetate copolymer and carbon black (EVA–CB) were synthesized for sensing BTEX (benzene, toluene, ethylbenzene and xylene) vapours. The composites were characterized using atomic force microscopy (AFM) in an electroconductive mode. Gas sensing results show that EVA-CB can reproducibly detect BTEX and that the response increases linearly with vapour concentration. Compared to gas-sensing measurements of gasoline vapours, the responses with toluene and ethylbenzene are different and can be explained by varying side chains of the benzene ring.
