TiO2 Nanoparticle-Modified Textiles for Sunscreen Applications: Advances and Challenges

Abstract

Under the backdrop of increasing ultraviolet radiation intensity and growing public concern about sun protection, the development of sun protection materials has become an important issue related to public health and quality of life. TiO2 nanoparticles, with their excellent light scattering and absorption properties, have shown great application potential in sun protection fabrics. Although current research has made certain progress in the preparation, testing and optimization of TiO2 nanoparticle-modified fabrics, there is a lack of comparative studies on the effects of different processes on the loading effect of TiO2 nanoparticles and the sun protection performance of fabrics. This study systematically summarizes the advantages and disadvantages of five modification methods and their impact on sun protection performance. At the same time, the research content will incorporate biological safety tests to reflect the impact of materials on human health and explore their potential in personalized sun protection, in line with the development trend of precision medicine. However, there are still problems to be solved in current research. The comparison of the loading effect of TiO2 nanoparticles and the sun protection performance of fabrics under different modification processes is not sufficient, and biological safety tests also need to be improved. Future research can further deepen process optimization, personalized customization, etc., to develop new types of sun protection fabrics with high efficiency, and promote the sustainable development and wide application of TiO2 nanomaterials in the field of sun protection.
