Introduction
摘要
Materials constitute one of the three major pillars of human social civilization. Depending on the primary materials used, the development of human society can be categorized into different eras, such as the Stone Age, Bronze Age, Iron Age, and the Synthetic Materials Age. In the early twentieth century, the first synthetic polymer material, phenol-formaldehyde resin, achieved industrial production. By the mid-twentieth century, polymer materials began to rapidly advance and permeate various aspects of human production and life, becoming essential foundational materials. This marked the commencement of the Polymer Materials Age in human society.
