摘要: Abstract An eco-friendly halochromic smart polymer was fabricated via covalently introducing azobenzene moieties into castor oil-based waterborne polyurethane. Infrared spectrum and thermogravimetric analysis have confirmed the successful incorporation of polyurethane chains. The undergoes color change from yellow to amaranth due structure shifting azo form hydrazine at pH
