PANI/Functionalized CNT/PVA nanocomposites were prepared by gamma irradiation technique, and their optical characterization were investigated. The results obtained showed that the bandgap derived from the UV–Vis study decreased with the increment of irradiation dose. There was a particular interaction between PANI and functionalized CNT upon irradiation indicating an interaction between these two functional materials. The surface morphology showed the thickness of the functionalized tube was greater after irradiation which indicated wrapping of the PANI onto the CNT wall.

γ辐照诱导的PANI /功能化MWCNTs / PVA纳米复合材料的光学表征

通过γ辐照技术制备了PANI /功能化CNT / PVA纳米复合材料，并对其光学特性进行了研究。获得的结果表明，UV-Vis研究得出的带隙随辐照剂量的增加而减小。辐照后，PANI和官能化CNT之间存在特定的相互作用，表明这两种功能材料之间存在相互作用。表面形态表明，辐照后功能化管的厚度较大，这表明PANI包裹在CNT壁上。
