Abstract

Graphical abstract: Highlights: Conductive PANi nanofibers were prepared by chemical oxidative polymerization. SEBS/PANi fiber membranes were prepared by electrospinning using a THF/toluene binary solvent. Under the high voltage electrostatic field, PANi nanofibers accumulated and electrochemically crosslinked on SEBS surface. The stretchable SEBS/PANi membrane has good corrosion resistance due to the unique micro-nano fiber structure. Abstract: Conductive PANi nanofibers were synthesized by chemical oxidative polymerization, and their morphology and structure were analyzed. SEBS and SEBS/PANi fiber membranes were prepared by electrospinning method, and the influence of THF/toluene binary solvent on fiber morphology was analyzed. Under the action of a high voltage electrostatic field, PANi migrates to the surface of the Taylor cone. With the rapid evaporation of THF, PANi nanofibers accumulate and electrochemically crosslink, forming a unique SEBS/PANi micro-nano fiber structure. The prepared electrospun SEBS/PANi membrane has a large strain recovery capability, and the thermal stability is remarkably improved as compared with the electrospun SEBS membrane. The electrospun SEBS/PANi membrane has good corrosion resistance to stainless steel, and the corrosion rate is greatly reduced, showing corrosion resistance even under large tensile deformation.
