The magnesium oxide component in composite conductive materials plays multiple important roles,mainly reflected in the following aspects:

Improving fatigue resistance:Nanoscale magnesium oxide particles can be effectively dispersed in the matrix material,reducing the generation and propagation of microcracks,thereby enhancing the fatigue resistance of composite materials.This is particularly important for mechanical equipment that requires long-term operation.

Improving thermal and dielectric properties:Low concentration doping of nano magnesium oxide helps to enhance the thermal and dielectric properties of nanocomposite dielectrics.For example,the magnesium oxide/polypropylene nanocomposite dielectric prepared by melt blending method with polypropylene as the matrix exhibits this characteristic.

Enhanced thermal conductivity:Magnesium oxide,as a part of the filler,can endow polymer composite materials with good thermal conductivity.This type of thermally conductive and insulating polymer composite material has the characteristics of excellent electrical insulation performance,corrosion resistance,easy processing and shaping,and light weight of polymer materials themselves.At the same time,it has good thermal conductivity in the filler part,so it is gradually replacing traditional materials in the fields of electronics and electrical appliances.

Improving the insulation performance of electrical materials:Magnesium oxide,as a wide bandgap insulation material,has received widespread attention for its excellent dielectric and adsorption properties in improving the insulation performance of electrical materials such as low-density polyethylene(LDPE)and cross-linked polyethylene(XLPE).

In summary,the magnesium oxide component in composite conductive materials improves the overall performance of the material through various mechanisms,including fatigue resistance,thermal properties,dielectric properties,thermal conductivity,and insulation properties.These characteristics make magnesium oxide an indispensable and important component in composite conductive materials.
