AB  - HYPOTHESIS: Superhydrophobic surfaces easily lose their excellent 
      water-repellency after damages, which limit their broad applications in practice. 
      Thus, the fabrication of superhydrophobic surfaces with excellent durability and 
      thermal healing should be taken into consideration. EXPERIMENTS: In this work, 
      robust superhydrophobic surfaces with thermal healing were successfully 
      fabricated by spin-coating method. To achieve superhydrophobicity, cost-less and 
      fluoride-free polydimethylsiloxane (PDMS) was spin-coated on rough aluminum 
      substrates. FINDINGS: After being spin-coated for one cycle, the superhydrophobic 
      PDMS coated hierarchical aluminum (PDMS-H-Al) surfaces showed excellent tolerance 
      to various chemical and mechanical damages in lab, and outdoor damages for 
      90days. When the PDMS-H-Al surfaces underwent severe damages such as oil 
      contamination (peanut oil with high boiling point) or sandpaper abrasion (500g of 
      force for 60cm), their superhydrophobicity would lose. Interestingly, through a 
      heating process, cyclic oligomers generating from the partially decomposed PDMS 
      acted as low-surface-energy substance on the damaged rough surfaces, leading to 
      the recovery of superhydrophobicity. The relationship between the spin-coating 
      cycles and surface wettability was also investigated. This paper provides a 
      facile, fluoride-free and efficient method to fabricate superhydrophobic surfaces 
      with thermal healing.
