2.1.2. Nanocoating

In a nanocoating process, a thin layer approximately less than 100 nm thickness is deposited on the substrate in order to improve certain properties or for contributing advanced functionality. Traditional coatings possess certain disadvantages such as (i) less durability, (ii) poor abrasion resistance, (iii) strength loss, (iv) less flexibility, and (v) improper adhesion between the substrate and coating layer (Nguyen et al., 2018, [64]). The aforementioned problems of traditional coatings could be solved by the utilization of nanocoatings (Joshi et al., 2011, [65]), (Smole et al., 2006, [66]), (Peng et al., 2019, [67]). The nanomaterial coating on fabrics will not influence their breathability or hand-feel (Temesgen et al., 2018, [68]).
