Transparent Slippery Surfaces Made with Sustainable Porous Cellulose Lauroyl Ester Films

In
recent years, liquid repellent surfaces have attracted considerable
attention because of their wide array of potential applications. In
the present study, slippery surfaces were fabricated using novel sustainable,
nanoporous cellulose lauroyl ester (CLE) films and slippery lubrication
fluid. The nanoporous CLE films were obtained after spray-coating
target surfaces using a nanoparticle suspension of CLE that was prepared
via nanoprecipitation. After the deposition of the slippery liquid
within the porous network, the obtained slippery surfaces exhibit
both excellent liquid repellency upon liquid impact and anti-icing
properties (by significantly retarding the icing time). Three-dimensional
droplet manipulation was also achieved on these surfaces by taking
advantage of the materials’ low contact angle hysteresis and
low adhesion property.
