Abstract:
The incorporation of polytetrafluoroethylen (PTFE) nanoparticles in curable polydimethylsiloxane (PDMS) matrix allows the formulation of superhydrophobic films with contact angles of ∼155-160°. Evaluation of the effect of PTFE particle size on the superhydrophobicity was conducted by using a larger particle size (2-5 μm); the resulting film yielded a contact angle of 140°. However, after UV irradiation, the surface gradually lost superhydrophobicity. Changes in surface chemistry resulting from these processes were investigated using X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). Applications for this superhydrophobic film include the coating of microelectronic devices for self-cleaning and moisture protection.
