Abstract

This work prepared super-hydrophobic hybrid thin films that are electric heatable. The hybrid film employed candle soot as template and were mechanically consolidate by sputtered silicon-oxide and fluorocarbon layers. The surface morphology and wettability were analyzed by Field Emission Scanning Electron Microscopy (FESEM) and contact angle measurement. The electric heating performance as stably super-hydrophobicity and thermally-manageable capability were characterized by AC voltages with various amplitudes and frequencies. The monitored nonlinear rise of surface temperature and the steady-state temperature were described by prediction equations. It is found that the silicon-oxide layer exhibits considerable importance of keeping super-hydrophobicity stable. The electric heating performance of hybrid thin film is beneficial to anti-icing, supply heating and heat preservation.
