Sažetak
The goal of this research was optimization of dip-coating application of ZnO nanoparticles on cellulose materials. Coatings on cellulose were prepared by dip-coating from 3- glycidyloxypropyltrimethoxysilane and characterized by SEM-EDX and FTIR-ATR. Optimization of sol-gel was performed by changing designing the experiment with six operational parameters: time, temperature, ultrasound power and concentrations of nanoparticles, acid and precursor. The optimization goal was maximal angle of recovery. Modification of cellulose materials was optimized by using State- Ease softwares program with Response surface methodology (RSM), Version 9.1. The results of optimization have shown that the best procedure for application of ZnO nanoparticles was: m(ZnO) = 0.071 g, catalizator HCl = 0.1 mol/L, ultrasound 80 kHZ. After modeling and calculation of the maximal angle of recovery, the calculated results were compared to the experimental values and the obtained relative error was very low (0.007-0.670 %) which proves that the model was well chosen. Therefore by this approach we were able to optimize the dip- coating process and to develop new materials foreseen as medicine textiles or food packaging materials with antimicrobial properties.
