一种物质与介质相互作用后(不论是化学的还是物理的),往往会出现性能的降解,这是腐蚀涵义的主要方面。另一方面,人们可利用金属腐蚀原理来进行电化学加工和酸洗,为人类服务。高聚物的腐蚀则主要表现在性能的降解,不过其腐蚀机理与金属腐蚀的不同。不论高聚物是晶体的,还是非晶体或交联的,都不会发生电化学作用。迄今对高聚物的腐蚀机理还很少论述,主要研 After a substance interacts with the medium (whether chemical or physical), degradation of properties often occurs, which is a major aspect of the meaning of erosion. On the other hand, people can use the principle of metal corrosion for electrochemical machining and pickling to serve human beings. Polymer corrosion is mainly manifested in the performance degradation, but its corrosion mechanism and metal corrosion of different. Electrochemistry does not occur whether the polymer is crystalline, amorphous or crosslinked. To date, the mechanism of corrosion of polymer is rarely discussed, the main research
