With　the　intensification　of　lunar　exploration,　the　failure　risk　caused　by　the　adsorption　of　lunar　dust　on　the　spacecraft　surface　cannot　be　ignored.　Therefore,　three　types　of　typical　spatial　solid　lubrication　films,　namely　polytetrafluoroethylene　(PTFE),　amorphous　carbon　(a-C)　and　molybdenum　disulfide　(MoS2),　were　prepared　as　test　samples.　Firstly,　the　surface　free　energy　parameters　of　the　material　were　measured　using　a　contact　Angle　measuring　instrument.　At　the　same　time,　atomic　force　microscopy　(AFM)　was　used　to　quantify　the　adhesion　of　the　film　samples　based　on　the　lunar　dust　micro-adsorption　model.　In　order　to　investigate　the　influence　of　the　test　environment,　the　environmental　pressure　was　adjusted　to　normal　pressure　environment　and　high　vacuum　environment　with　a　vacuum　degree　of　10−6Pa　for　testing.　The　results　indicate　a　positive　correlation　between　surface　energy　and　adhesion.　As　surface　energy　increases,　molecules　tend　to　move　closer,　forming　a　stronger　attraction　and　thus　enhancing　surface　adhesion.　In　addition,　AFM　was　used　to　measure　the　adhesion　force　under　atmospheric　pressure　and　vacuum　conditions,　revealing　that　parameters　measured　in　atmospheric　environment　were　generally　higher　than　those　measured　in　vacuum,　which　effectively　verified　the　existence　of　capillary　force　in　the　microscopic　adsorption　model　and　its　influence　on　the　adhesion　effect.　Through　the　test　comparison　of　three　groups　of　typical　solid　lubricating　films,　it　is　found　that　MoS2　has　a　lower　adhesion　effect　than　the　other　two　groups　of　films,　which　can　effectively　reduce　the　adhesion　phenomenon　of　lunar　dust　on　the　surface　of　the　material,　and　provide　suitable　materials　for　future　lunar　exploration　and　manned　lunar　missions.　©　The　Author(s)　2025.
