Reports from Anhui University Advance Knowledge in Applied Surface Science

June 6, 2014



By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Science are presented in a new report. According to news reporting from Huainan, People's Republic of China, by NewsRx journalists, research stated, "Titanium nitride (TiN) nano-particles were modified by the grafting of a random copolymerization functionalized macromolecular coupling agent (F-MCA) via a direct blending method. The hydroxyl groups on the surface of the nano-TiN particles interact with the silanol groups [-Si-OCH3] of the F-MCA to form an organic coating layer."

The news correspondents obtained a quote from the research from Anhui University, "The formation of covalent bonds [Ti O Si] was verified using Fourier transform infrared spectroscopy. An X-ray diffraction analysis suggests that the presence of the F-MCA inhibited the growth of the crystal plane but did not change the crystal structure of the TiN. Thermogravimetric analysis and contact angle measurement indicated that the F-MCA molecules were adsorbed or anchored to the surface of the nano-TiN particles, which hindered their aggregation. Pristine nano-TiN particles are poorly dispersed in ethyl acetate. Compared with the pristine TiN particles, the modified TiN particles show good dispersibility and form a stable colloidal dispersion in ethyl acetate. The surface hydrophobicity of the modified TiN increases, and the F-MCA molecules are anchored on the surface of the TiN particles."

According to the news reporters, the research concluded: "TiN particles modified by a F-MCA can be used in polymer blends, thermoplastic elastomers and polymer nanocomposites that have a better performance and longer life cycle."
