Description

1: Technical field

[0001] The present invention relates to the field of polymer processing, and more particularly, the present invention relates to the preparation of polymer-based nanocomposites. Two: background technology

[0002] A nanocomposite material refers to a material in which at least one of the dispersed phases has a one-dimensional scale within 100 nm. Nanocomposites have higher heat deflection temperature, strength, stiffness, thermal barrier properties and low gas / liquid permeability. Since Roy and Kormarneni et al. (Roy R, Kormarneni S, et al. [J]. Mater Res Symp Proc, 1984, 32: 347) first proposed the concept of nanocomposites in 1984, nanocomposites have become a material scientist. research hotspot. Inorganic nanoparticles involved include silicon dioxide (SiO 2 ), calcium carbonate (CaCO 3 ), titanium dioxide (TiO 2 ), and silicates with layered structures such as montmorillonite, hydrotalcite, expanded graphite and vermiculite, covering polymers inc...
