Abstract
We have investigated the possibility of controlling wet snow sliding with maintaining good anti-snow adhesion on super-hydrophobic surface by providing hydrophilic channels. We formed gutters on a base material and prepared 3-dimensional combined surface whose top is hydrophilic and both its side and bottom are super-hydrophobic. We also prepared 2-dimensional combined surface in which hydrophilic channels are formed in a super-hydrophobic surface. The former surface effectively formed water channel on the top of the gutter and exhibited good sliding performance for wet snow, whereas the latter was vice versa. The cause of this difference was discussed.
