The research is aimed at addressing the problem of ensuring prolonged antimicrobial action of composite coatings for textile materials. The application of ZnO nanoparticles modified with a bifunctional organosilane within polymercolloidal finishing compositions for the final treatment of fabrics is proposed. The paper presents the results of a study on the effect of organosilane surface modification on ZnO nanoparticles, which were preliminarily synthesized using an improved resource-saving direct precipitation method from an aqueous solution. 3-glycidoxypropyltrimethoxysilane (GPTMS) was selected as the modifying agent, which contains an epoxy functional group in addition to methoxy groups. The amount of GPTMS used for modification was 1.5 mmol per 1 g of synthesized ZnO nanoparticles. The modification reaction was carried out at a temperature of 70 °C for 3 hours, followed by precipitation, washing, and drying of the nanoparticles. Evaluation of the modified ZnO samples was conducted by studying the morphological structure of the nanoparticles using scanning electron microscopy (SEM) and elemental analysis by energy-dispersive X-ray spectroscopy (EDX). Analysis of the micrographs established that modification with the selected organosilane promotes a reduction in the degree of agglomeration of ZnO nanoparticles. Elemental composition analysis revealed the presence of Si in the modified ZnO sample, confirming the formation of an organosilane layer on the nanoparticle surface. The scientific hypothesis regarding the enhancement of nanofiller immobilization stability in the acrylic polymer matrix through the introduction of an epoxy functional group as a result of surface modification of ZnO nanoparticles with 3-glycidoxypropyltrimethoxysilane is substantiated.
