摘　　要：Edible Lubricant-Infused Surface(ELIS)was fabricated through antisolvent method by adding ethyl oleate(lubricant/antisolvent),ethanol(solvent)and shellac(solute/base layer of ELIS)into an all-in-one solution to in-situ prepare ELIS through single step of solvent evaporation.The ELIS comprising sub-micro-to micro-scaled shellac particles shows water and food liquid slippery,transparency,stability against abrasion and lubricant retaining ability against sheer force.Using all edible material to fabricated ELIS is a more efficient route for application when compared with other Lubricant-Infused Surface(LIS).Traditional fabrication for LIS included steps such as:base layer fabrication,lubricant infusion,excess lubricant removal,UV light treatment and chemical etching.The method proposed in this article could further simplify the preparation to an all-in-one solution and simplify the synthesis process to only 60-degree heating.Furthermore,Shellac ELIS coating could withstand abrasion and hold performance when compared with other ELIS coatings.
