Abstract: | A facile, green method was explored for the organic-inorganic complex coating with superhydrophobic and transparent property on glass matrix. The glass surface was firstly treated with polyethylene glycol (PEG) and SiO2 organic-inorganic solution and then modified with a layer of 1,1,1,3,3,3-Hexamethyldisilazane (HMDS). The glass samples were characterized by scanning electron microscopy (SEM), water contact angle (CA) measurement, and UV–Vis spectrophotometry. The results showed that the optical transmission over the visible range up to 89 % (in reference to 100 % transmission defined by bare glass substrate), and the water CA of the film reached 168°. Superhydrophobic coatings with excellent optical transmittance will have potential applications in our daily life. |
