SELF-CLEANSING SUPER-HYDROPHOBIC POLYMERIC MATERIALS FOR ANTI-SOILING |
摘要 |
Disclosed are optically transparent super-hydrophobic materials, and methods for making and using the same, that can include an optically transparent polymeric layer having a first surface and an opposing second surface. At least a portion of the first surface has been plasma-treated with oxygen and a fluorine containing compound. The treated surface includes nano- or micro-structures that are etched into the first surface and that are chemically modified with the fluorine containing compound. The nano- or micro-structures have a height to width aspect ratio of greater than 1, and a water contact angle of at least 150°. The optically transparent polymeric layer retains its optical transparency after said plasma-treatment. Due to their optical transparency, chemical and thermal robustness, weatherability, and self-cleaning performance, the super-hydrophobic materials disclosed are useful in high performing solar cell units in harsh semi-arid environments. |

1. An optically transparent super-hydrophobic material comprising an optically transparent polymeric layer having a first surface and an opposing second surface, wherein at least a portion of the first surface has been plasma-treated with oxygen and a fluorine containing compound, wherein the treated surface includes:
(i) nano- or micro-structures that are etched into the first surface and that are chemically modified with the fluorine containing compound, wherein the nano- or micro-structures have a height to width aspect ratio of greater than 1; and (ii) a water contact angle of at least 150°, wherein the optically transparent polymeric layer retains its optical transparency after said plasma-treatment. |
