Superhydrophobic (SHO) surfaces have drawn great attention thanks to their theoretical significance and myriad applications in industry and everyday life. Current approaches to fabricate such surfaces require calcinating at high temperatures, tedious and time‐consuming treatments, toxic chemicals, and/or processing with intricate instruments. Long‐duration SHO surfaces are even more challenging due to material instability and easy contamination by organic pollutants in dry conditions. To overcome these difficulties we design a simple approach via self‐supplying of low surface tension chemicals to nanoparticles to fabricate multifunctional SHO heterostructures. The method herein features room temperature, rapid processing, with environment‐friendly raw materials. With multiple functions such as photocatalysis and transparency SHO surfaces further extend their lifetime and enable self‐sustaining environment maintenance.
