Construction And Application Of A Hollow Polyaniline Hybrid Fiber

Conductive polymers have received extensive attention because of their unique internal structure and electrical properties.Among these conductive polymers,Polyaniline is a special material.The special oxidation state of Polyaniline gives it unparalleled conductivity,which makes it applicable in many fields.In the past decades,Polyaniline nanofibers have been prepared in many ways.Synthesis of Polyaniline in aqueous solution will enhance its processability,and the increase of the relative surface area will also have a positive effect on the preparation of Polyaniline nanofibers.Polyaniline also has a good prospect in commercial applications.In this paper,a kind of polyamide acid fiber was prepared by electrospinning method,and then hollow Polyaniline fiber was prepared by using this fiber as template.CuO/PANI hollow hybrid fiber material was prepared by doping copper oxide nanoparticles on the surface of Polyaniline.The material has good conductivity,large specific surface area,and has great advantages in electrochemical sensors.We characterized it by many instruments,and analyzed its performance.CuO/PANI hollow hybrid fiber was used as electrode material for the detection of hydrogen peroxide and glucose.The cyclic voltammetry curve,current and time response curve,anti-interference curve,stability and service life test were carried out respectively.The CuO/PANI hollow hybrid fiber electrode was analyzed and summarized.It is found that our sensors have better current response than other materials,which indicates that our electrode materials are more sensitive.In addition,the CuO/PANI electrode prepared by us can detect both hydrogen peroxide and glucose at the same time,which has greater application potential in practical applications.
