Research progress of durable,transparent and smooth repellent surfaces
Recently,smooth liquid-repellent surfaces(SLRS)with excellent anti-wettability have become a prominent subject of research in both academia and industry.Although the applications of liquid-repellent sur-faces with anti-wettability are increasingly growing,new challenges and requirements are also emerging.High transparency,well mechanical/chemical durability,and long-term weather-resistance are essential prerequisites for the practical implementation(such as anti-fouling for photovoltaics,anti-icing for wind power,and anti-scaling for pipelines)of smooth liquid-repellent surfaces.Therefore,there should be an emphasis on achieving these qualities.This review describes the classification and preparation of liquid-repellent surfaces.The applica-tions of durable SLRS in self-cleaning,anti-fingerprint/anti-smudge,de-icing/anti-icing,anti-biofouling,and anti-scaling are discussed,followed by a summary of the challenges and an outlook on future research.
