Polymer　nanocomposites　have　attracted　extensive　research　interest　because　of　their　unique　properties,　and　will　become　one　of　the　hotspots　in　the　field　of　material　research　in　the　future.　It　partly　overcomes　the　defects　in　the　performance　of　single　materials　and　traditional　composites,　so　that　the　materials　have　both　the　advantages　of　inorganic　materials　(such　as　rigidity,　high　thermal　stability　and　special　optical　and　electromagnetic　properties)　and　the　advantages　of　polymer　materials　(such　as　elasticity,　dielectric,　ductility　and　processability).　Moreover,　because　inorganic　particles　are　uniformly　distributed　in　the　form　of　nanoparticles　in　the　polymer　body,　Therefore,　this　kind　of　nanocomposites　often　have　some　special　applications　in　the　fields　of　mechanics,　heat,　electricity,　optics,　nonlinear　optics　and　so　on.　©　2023,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
