Abstract

Superhydrophobic surfaces have demonstrated exceptional efficacy in combatting biofouling contaminations of optical devices and equipment in marine applications.However,the fabrication of highly transparent superhydrophobic materials remains a formidable challenge due to the inherent trade-off between surface roughness for superhydrophobicity and optical transparency.Herein,we design a robust and transparent superhydrophobic coating(Si-POSS)embedded silica nanoparticles(200 nm)with fluorinated polyhedral oligomeric silsesquioxanes(F-POSS)and zinc pyrithione(ZPT).The Si-POSS coating exhibits excellent water repellence toward diverse liquids and optical transmittance exceeding 90%in the visible spectrum.Moreover,the Si-POSS coating sustains long-term anti-bacterial(>99.11%)and anti-algal effects for over 30 days,accompanied by mechanical,chemical,and thermal stability.This research asserts that the Si-POSS coating with outstanding combined characteristics holds significant potential for marine applications,particularly in self-cleaning and antifouling endeavors.
