Raw　lacquer　(RL),　ethanol　being　used　as　the　solvent,　was　added　to　polyvinyl　pyrrolidone　(PVP)　and　then　electrospun　into　RL/PVP　nanofilms.　Manufacturing　parameters　such　as　RL/PVP　ratio,　voltage,　flow　velocity,　needle　type,　and　the　distance　between　syringe　and　the　collection　board　were　systematically　investigated.　A　scanning　electronic　microscope　(SEM)　was　used　to　observe　the　surface　morphology　of　nanofilms;　the　block　drop　method　was　used　to　measure　the　water　contact　angle;　the　mechanical　properties　of　RL/PVP　nanofilms　of　different　proportions　were　tested　by　universal　material　testing　machine;　and　Fourier-transform　infrared　spectroscopy　(FT-IR)　was　used　to　characterize　the　structure.　Based　on　the　water　resistance　and　acid　resistance　measurements,　the　proposed　nanofilms　demonstrated　to　be　water　and　acid　resistant　were　successfully　produced.　The　results　show　that　PVP　that　melts　in　water　becomes　incompatible　with　water　after　adding　raw　lacquer,　and　the　acid　resistance　is　greatly　improved.　Furthermore,　the　smaller　the　fiber　diameter,　the　better　the　mechanical　properties　of　the　nanofilms　are　under　low　ratio　of　RL/PVP.　With　a　high　proportion　of　RL/PVP,　the　inner　structure　of　the　nanofilm　is　denser,　and　the　water　resistance　and　acid　resistance　are　better.　The　dense　structure　can　protect　the　inner　material　of　the　nanofilms.
