On the Gating Mechanism of Slippery Liquid Infused Porous Membranes

Slippery liquid infused porous surfaces owe some of their remarkable properties such as low fouling, multiphase transport without clogging, and self-healing to the presence of liquid lined pores. In this paper, the gating mechanism of liquid infiltrated porous membranes is investigated. The liquid film thickness lining the pores is experimentally obtained and correlated to annular two phase flow model
