Development of multi-functional cotton fabrics with Ag/AgBr-TiO2 nanocomposite coating

Significance Statement

Cotton is one of the most abundant natural materials, and has been widely used in our daily life. Despite the excellent properties and low cost of cotton fabrics, some characters like the impotent antimicrobial activity, low strength and poor sensitivity to the UV light, confine their wide applications, especially in some high-end areas. Value addition to cotton by functionalization has generated considerable academic and industrial attention, not only due to their potential use in physical, ther­mal, biological and medical protection, but also to meet the constantly evolving demand from consumers for advanced materials.

A team led by Professor Peng-Cheng Ma in the Xinjiang Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, reported the development of multi-functional cotton fabrics with Ag/AgBr-TiO2 nanocomposite coating, aiming at enhancing the technical value of fabrics using a simple spray coating process. The results showed that the introduction of nanocomposite coating onto cotton fabrics significantly enhanced the mechanical properties under both warp and weft directions, along with a rectified surface property from the hydrophilic to the hydrophobic. More interestingly, the developed fabrics showed excellent antibacterial, selective oil adsorption from oil-water mixture and UV blocking activities, thus significantly enhancing the technical value of cotton fabrics. The authors anticipate that the developed cotton fabrics could be a promising candidate for medical, personal hygiene and environmental applications.

Abstract

This paper reported the preparation of multi-functional cotton fabrics with Ag/AgBr–TiOnanocomposite coating, aiming at enhancing the technical value of fabrics using a simple spray coating process. Various techniques were employed to characterize the changes on the mechanical, surface and physical properties of fabrics before and after coating. The results showed that the introduction of nanocomposite coating onto cotton fabrics significantly enhanced their mechanical properties under both warp and weft directions, along with a rectified surface property from the hydrophilic to the hydrophobic. More interestingly, the developed fabrics exhibited excellent antibacterial, selective oil adsorption behavior from oil-water mixtures and UV blocking activities, thus significantly enhancing the value of cotton fabrics for various applications.
