| Abstract: |
| In this study， an environmentally friendly and efficient anti-adhesion coating for paper using food-grade raw materials were developed， specifically paraffin and fumed silica. The effects of coating amount， the mass ratio of paraffin to modified fumed silica nanoparticles （HSNPs）， and heat treatment temperature on the wettability of the coated paper were investigated. Additionally， the mechanical properties， acid and alkali resistance， and anti-adhesion characteristics of the coated paper were examined. The results indicated that when the coating amount was 8 g/m²， the mass ratio of paraffin to HSNPs was 1∶5， and the heat treatment temperature was 120 ℃， the paraffin/HSNPs coated paper retained its superhydrophobic properties even after undergoing 12 friction cycles， 6 000 water drop impacts， and 20，000 bending tests， etc., respectively. After paraffin/HSNPs coating was applied to paper cups， the coated paper cups could exhibit excellent anti-adhesion effects against various viscous liquids. |
