The　accurate　measurement　of　tiny　pressure　variations　in　low-pressure　environments　requires　pressure-sensitive　paint　(PSP)　with　high　pressure　sensitivity　and　pressure-sensitivity　constancy　for　aerodynamics　testing.　In　this　study,　polymer-ceramic　pressure-sensitive　paints　(PC-PSPs)　were　developed　using　platinum(II)　meso-tetra　(pentafluorophenyl)　porphyrin　(PtTFPP)　and　palladium(II)　meso-tetra(pentafluorophenyl)　porphyrin　(PdTFPP)　as　luminophores;　titanium　dioxide　(TiO2)　and　mesoporous　silica　(mSiO2)　as　particles;　and　poly[1-(trimethylsilyl)1-propyne]　(PTMSP),　poly(isobutyl-methacrylate)　(PIBM),　ethylene-vinyl　acetate　copolymer　(EVA),　and　polyacrylate　(B1000)　as　polymers.　The　static　characteristics　were　calibrated　and　evaluated　under　low-pressure　conditions.　The　results　showed　that　PC-PSPs　using　PtTFPP　with　a　short-lifetime　and　high　oxygen-permeable　polymer　led　to　high　pressure　sensitivity.　By　contrast,　if　PdTFPP　with　a　long-lifetime　was　used,　the　pressure　sensitivity　was　dominated　by　the　luminescence　lifetime　rather　than　the　oxygen　permeability　of　the　polymer.　PdTFPP/mSiO2-PTMSP　exhibited　a　remarkable　pressure　sensitivity　of　78.46%/kPa.　PC-PSPs　employing　PIBM,　EVA,　and　B1000,　respectively,　exhibited　excellent　pressure　sensitivity　constancy　above　96%　after　near-vacuum　storage　for　one　hour.　However,　PTMSP-based　PC-PSPs　exhibited　poor　pressure-sensitivity　constancy　owing　to　the　aging　of　the　polymer　in　vacuum,　which　can　be　improved　by　employing　the　long-lifetime　PdTFPP　luminophore　and　mSiO2　particles.　Furthermore,　PC-PSPs　using　mSiO2　particles　exhibited　lower　signal　levels,　higher　pressure　sensitivities,　lower　temperature　dependencies　and　photodegradation　than　those　using　TiO2　particles.　PdTFPP/　mSiO2-PIBM　and　PdTFPP/mSiO2-B1000　exhibited　application　potential　under　low-pressure　conditions　owing　to　their　favorable　static　characteristics.
