[0002] Polymer materials, also known as polymer materials, are materials composed of polymer compounds as the matrix and other additives. Polymer materials are a type of polymer material with high molecular weight, good mechanical properties, heat resistance and chemical stability, and therefore are widely used in engineering materials, medical devices, electronic devices and other fields.
