Abstract：

A　flexible　hybrid　film　consisting　of　graphene　nanoplatelets　(GNPs)　and　multi-walled　carbon　nanotubes　(MWCNTs)　was　prepared　and　employed　as　a　multifunctional　sensor　to　monitor　temperature　and　liquid　leakage,　based　on　the　piezoresistive　effect.　The　influences　of　the　GNP　content　on　the　mechanical,　thermal,　and　sensing　properties　were　investigated.　Experimental　results　showed　that　both　the　hardness　and　Young’s　modulus　of　the　hybrid　film　were　decreased　with　an　increasing　GNP　content,　while　the　thermal　conductivity　exhibited　in　an　opposite　trend.　The　electrical　resistance　of　the　hybrid　film　decreased　was　linearly　with　an　increase　in　temperature.　The　resistance　change　increased　linearly　with　an　increase　of　the　solvent　adsorption.　These　features　demonstrated　the　potential　applications　of　the　hybrid　film　in　the　detection　of　temperature,　and　liquid　leakage.　The　sensitivity　of　leakage　detection　is　increasing　with　the　increase　of　the　GNP　loading,　while　temperature　sensitivity　is　in　the　opposite　trend.　©　2019　by　the　authors.
