【Abstract】 The effective construction of special morphologies on the surface of micro and nanofibers is the most efficient way to broaden their application areas. Groove morphologies have garnered increasing attention due to their unique structure and properties. Methods for creating groove morphologies on the surface of micro and nanofibers using electrospinning technology are reviewed, including void-elongation and wrinkle-elongation based on the phase separation principle, selective dissolution methods based on post-processing principles, and composite electrospinning methods based on in-situ construction principles. In comparison, in-situ construction composite electrospinning methods exhibit simple processes, diverse polymer compositions, and strong controllability over groove morphology(quantity, spacing, depth), which has greater research value and broader application prospects. The polymers for preparation of grooved morphology micro and nanofiber are extensive. The application areas of grooved morphology micro and nanofibers are also detailed, encompassing cell culture, wetting property regulation, and wastewater treatment.更多还原
