In order to improve the mechanical properties of SMPU
vapor grown carbon fiber(VGCF) reinforced SMPU composite films with various VGCF contents were prepared via a solution mixing method.The mechanical and shape memory properties of the pure SMPU and VGCF/SMPU composite films were studied.The results show that
the VGCF still shows good dispersion in SMPU when the VGCF content reaches 9 wt% in the prepared composite film.The tensile strength and stiffness of the prepared composite films are greatly improved after compounding SMPU with VGCF
the tensile strength is improved by 66% with adding 9 wt% VGCF in the composite film
the elastic modulus is improved by 300% at this content and the storage modulus is also greatly improved.The shape memory property of the composite film is decreased after compounding SMPU with VGCF
while its shape memory property can be close to that of the pure SMPU after appropriate pretreatment.
