Abstract: Silicone nanotubes with small diameter,long length and thin wall thickness are prepared by sol-gel method.Polymerization inhibitor is added modify the surface of nanotubes prepared.The structures of the samples are characterized.The samples,commercial activated carbon (AC) and silica gel (SG) are compared through the experiments of static adsorption against water vapor,n-hexane and oil vapor respectively.These three adsorbents respectively are also used to carry out dynamic adsorption experiments on a self-made n-hexane adsorption device.The adsorption results show that the static/dynamic adsorption capacity and stability of the prepared silicone nanotubes are much higher than that of commercial AC and SG.
