Nanoparticles when combined with conducting polymer polyaniline leads to increase in advanced functional properties. Cu, Ni and Zn metal oxide (CNZMO) nanoparticles were synthesizes by sol-gel technique. Conducting polymer polyaniline was synthesized by low temperature chemical synthesis method. In situ technique was used to synthesize CNZMO-Polyaniline (PANI) nanocomposite. Metal nanoparticles, polyaniline and metal oxide-polyaniline nano-composite were characterized by UV–visible, FTIR, FESEM, XRD and TGA/DTA techniques. Opto-electronic, thermal and anticorrosive properties of CNZMO-PANI nano-composite was compared with their bulk counterpart. The optical band gap of the PANI-nano-composite was found to be 1.72 eV which is lesser than pure polyaniline (3.2 eV) and bulk counterpart (2.2 to 3.6 eV). Anticorrosive property of CNZMO-PANI nano-composite was tested for mild steel in 0.1 N hydrochloric acid medium and was found to be good corrosion inhibitor at 80 ppm concentration. CNZMO-PANI nanocomposite was found to be thermally stable up to 650 °C. Hence, synthesized CNZMO-PANI nano-composite has large number of applications in the field of nano-electronics, heat resistance composite material, optoelectronics and as anticorrosive material.

聚苯胺-金属氧化物-纳米复合材料,用作纳米电子学,光电学,耐热性和防腐材料

当纳米颗粒与导电聚合物聚苯胺结合时,会导致高级功能特性的增加。通过溶胶-凝胶技术合成了Cu,Ni和Zn金属氧化物(CNZMO)纳米粒子。通过低温化学合成法合成了导电聚合物聚苯胺。原位该技术被用于合成CNZMO-聚苯胺(PANI)纳米复合材料。通过紫外可见,FTIR,FESEM,XRD和TGA / DTA技术对金属纳米颗粒,聚苯胺和金属氧化物-聚苯胺纳米复合材料进行了表征。比较了CNZMO-PANI纳米复合材料的光电,热和防腐性能。发现PANI-纳米复合材料的光学带隙为1.72 eV,小于纯聚苯胺(3.2 eV)和本体对应物(2.2至3.6 eV)。测试了CNZMO-PANI纳米复合材料在0.1 N盐酸介质中对低碳钢的防腐性能,发现其在80 ppm浓度下是良好的腐蚀抑制剂。发现CNZMO-PANI纳米复合材料在高达650°C的温度下具有热稳定性。因此,
