摘　　要：Deep understanding has been achieved for nanotechnology,which has greatly advanced the development of technology.The adsorption property,as one of conventional properties of nanomaterials,is well known but has not been fully applied.In this paper,nanomaterials were used as adsorbents,and further their adsorption properties on substrates were studied.Spherical nano-silica was selected as a representative,which was labeled with a dye.The chemical bonding between the dye and nano-silica was confirmed by Fourier transform infrared(FTIR)spectroscopy.It was proved that the adsorption was a spontaneous,endothermic and entropy increase process.The adsorption model conformed to the Langmuir-type adsorption model.Reaction kinetic studies showed that the number of reaction stages in the adsorption process was about 1.45.The adsorption state was studied to verify the existence of nanomaterials as an adsorbent on the surface of the polymer,and then provided a demonstration for feasibility of the general polymer surface modification method.
