A polypropylene fabric woven from a plurality of polypropylene fibers comprises a first surface and a second surface, at least one of the first surface and the second surface is treated with electro-optical treatment.

Radiation-curing bio-based durable topcoats or coatings and a radiation cure method of producing leather alternatives are disclosed. Biobased non-isocyanate poly(hydroxyl urethane) (NIPU), biobased polyesters, biobased polyethers, biobased polycarbonates, and biobased polyamides can be readily synthesized, and further modified with biobased acryloyl chloride, methacryloyl chloride, or itaconic anhydride into biobased radiation curable prepolymers. Through formulating such obtained biobased prepolymers with biobased acrylate and biobased methacrylate monomers, and using a radiation cure method, durable topcoats and leather alternatives with low environmental footprints can be obtained.
