In terms of wearable products, compact WPU coatings often cause discomfort due to the intrinsic poor vapor transmission. Moreover, the resultant relatively high humidity promotes the growth of skin flora, resulting in unpleasant odors, and even skin infectious diseases. To this end, breathable porous WPU coatings with tunable pore size has emerged as a favorable alternative to modulate the “climate” of microenvironment at the interface between skins and wearable products. Several strategies have been now developed to engineer porous WPU coatings. In this perspective, we describe various strategies that have been developed to manufacture porous WPU coatings. According to whether the template is used and the category of templates used, we categorize these strategies into three different types, including hard templating, soft templating, and template-free methods. We discuss the advantages and disadvantages of each strategy and highlight the importance in developing new strategies of making highly breathable WPU to help the sustainable growth of the leather industry.
