Halloysite nanotubes(HNTS)loaded with methyl methacrylate(MMA)and phase change materials are used as carrier to construct hybridized aerogel(HGA)together with modified graphene oxide.Polymer nanowires are formed through polymerizing monomers in HNTS lumen.Polymer nanowires interact with adjacent graphene(GO)nanosheets to closely connect HNTS and GO to form three-dimensional(3D)porous hybrid aerogel.Loads are efficiently transported among GO nanosheets,HNTS,and polymer nanowires as the samples are force-loaded.Successful preparation of HGA is demonstrated through SEM,FT-IR,specific surface area,and pore size tests.The stress-transfer behavior of hybridized aerogel is studied by means of compressive property tests and laser microscopic Raman spectroscopic characterization.Phase change behavior of the aerogel material is analyzed,and the thermal properties are tested.Study results show that both PMMA polymer chains and HNTS can enhance the structure of HGA,and the phase change material in HGA changes its phase at low temperature,and provides a promising thermal insulation property.
