Based on the unique surface effect,hollow structure and high mechanical strength of the carbon nanotubes (CNTs),CNTs were introduced into porous polymer.The porous polyimide polymers with different content CNTs were prepared by coldpressing sintering.The porosity,morphology and oilcontaining performance of the porous polymers were studied.The results show that the porosities of the porous polymers are increased after filled with CNTs.The biggest porosity of the porous polymer is up to 42.2%.The CNTs adhere well on the surface of polyimide microballs and this will improve the adsorption of the pore surface of the porous polymer.Compared with the porous polymer material without CNTs,the oil content and the oil holdup of the porous polymers filled with CNTs are greatly increased.
