Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of foam material preparation, and in particular relates to an environment-friendly polymer foam material. [0003] 【Background technique】 [0004] Foam material is also called porous material. It is made of resin as the main raw material and has countless micropores inside. It has the functions of light weight, heat insulation, shock resistance and corrosion resistance. It is widely used as packaging materials and car and ship shells. [0005] In 2004, Geim and Novoselov of the University of Manchester in the United Kingdom obtained independent two-dimensional graphene (Gra-phene, GN) crystals by stripping highly oriented graphite through tape, and graphene has become a research hotspot in the field of materials science. one. Graphene is actually a single atomic layer of graphite, which has a unique two-dimensional structure and excellent mechanical, thermodynamic, optical and electrical properties....
