UV and gamma irradiation effects on surface properties of polyurethane derivate from castor oil

[摘要] Gamma and ultraviolet radiation effects on hardness, elastic modulus and viscoelastic properties of polyurethane derived from castor oil (PU) were investigated by nanoindentation tests. Modifications on surface morphology, induced by radiation, were obser
