Investigation of thermal, mechanical behavior, and contact angle measurements of poly(vinyl chloride) based nanocomposite films containing coated CuO nanoparticles with thiamine

In the present study, solution casting method was used for the preparation of nanocomposite films. Primarily, the surface of copper (II) oxide (CuO) nanoparticles was modified with biosafe molecules such as citric acid and ascorbic acid for better dispersion in the polymer matrix. Then novel nanocomposite films were fabricated by loading various percentages of modified CuO nanoparticles in the poly(vinyl chloride) matrix. The ultraviolet (UV)-blocking effects of nanocomposites and their optical properties were studied using UV-visible spectroscopy. Also, other analyses, including Fourier transform infrared spectroscopy, mechanical tensile test, thermogravimetric analysis, and X-microscopy, were performed for investigating thermal, mechanical, and morphological properties of the hybrid materials.

Crystalline hydroxyapatite (HA) and 0.8 wt.% silicon-substituted HA (SiHA) thin films were produced using magnetron co-sputtering. These films were subjected to contact angle measurements and in vitro cell culture study using human osteoblast-like (HOB) cells. A wettability study showed that SiHA has a lower contact angle, and thus is more hydrophilic in nature, as compared to HA. Consequently, enhanced cell growth was observed on SiHA at all time-points. Furthermore, distinct and well-developed actin filaments could be seen within HOB cells on SiHA. Thus, this work demonstrated that the surface properties of the coating may be modified by the substitution of Si into the HA structure.
