The results showed that value and air permeability of the prepared paper-based composites that depositing modified and of unmodified LCMNF were significantly reduced to and ⩽0 . 0 0 3 μ m/ ( P a⋅ s) ,respectively,which were 16. 2 % and 0 . 0 2 % ofthoseoftheoriginal paper.Meanwhile,the kitvalue increased fromOto12,demonstratingasignificant enhancement in oil-proof performance.
