Sažetak
Polymer surface modification has gained a lot of interest over the last few decades. The surface modification offers new physical and chemical properties to polymers by changing their surface properties or incorporating metal or metal oxide nanoparticles [1, 2]. Nanoparticles have a significant role due to their unique magnetic, electrical, mechanical, optical, and electronic properties with respect to the bulk materials. Zinc oxide (ZnO) is one of the most widely used materials with unique physicochemical properties and direct band-gap energy of 3.37 eV, making him a good UV absorber [3]. Polymer/nanoparticle composites gain attention due to their excellent properties for applications in the food industry, biomedicine, biotechnology, optoelectronics, etc. In this work, PVC (polyvinyl chloride) and HDPE (high-density polyethylene) polymers were treated with an atmospheric pressure plasma jet using helium as a working gas. The ZnO colloidal solution was synthesized using pulsed laser ablation in water. After plasma treatment, ZnO colloidal solution was dropped on the polymer surface, and, finally, the polymer was treated again with helium plasma. Optical emission spectroscopy (OES) was used to determine the elemental composition of plasma. All polymer samples (treated and untreated) were characterized using Fourier-transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The ZnO optical properties, crystalline structure, elemental composition, morphology, and nanoparticle size distribution were studied using UV-VIS spectrophotometer, X-ray diffraction (XRD), X-ray spectroscopy (XPS), and scanning electron microscope (SEM), respectively.
