This work presents a study about the synthesis by plasma of organometallic compounds of titanium oxides (TiO) obtained from titanium tetraisopropoxide (TTIP) and water on polyethylene (PE) to form TiO-PE superficial composites. The objective is the synthesis of TiO nano and meso particles attached on PE supports. The synthesis was carried out by plasma in a vacuum tubular glass reactor at 13.56 MHz, 10−1 mbar and 100-150 W. The accelerated particles in the plasma have the function of separating the organic and inorganic segments of TTIP bonding the TiO particles with PE. The resulting TiO-PE superficial compounds have agglomerates of spherical and oval organometallic particles with diameter between 50 and 3000 nm as a function of the time of synthesis. The agglomerates contain Ti and C oxides with a tendency to change from film to particles as a function of the energy applied in the synthesis. The contact angles of the superficial composites varied from 40° to 76°. [ABSTRACT FROM AUTHOR] |
