摘要: Abstract In this paper, dope dyeing method was adopted in preparation of polyurethane/β-cyclodextrin/disperse orange 31 solutions. The solutions were cast into films. Characterizations the structure and properties films investigated by FTIR, UV–vis spectra, mechanical test, DMA TGA. results revealed that dope-dyed polyurethanes had good dye fastness, increased thermal properties, which could be ascribed to existence hydrogen bonding between β-CD polyurethane. rheological measurements showed dope-dyeing solution a pseudo-plastic non-Newtonian behavior Index with increasing temperature.
