Research Progress of Life Prediction of Polymer Coating
The service life is an important indicator of polymer coatings.The research progress in predicting the life of polymer coatings was reviewed.Common failure mechanisms of polymer coatings were introduced,including internal factors such as coating structure and composition,as well as external factors such as light,heat,and humidity.The recently applications of artificial neural networks,grey model,Arrhenius law and other models in life prediction of polymer coatings were reviewed.The prospect of polymer coating life prediction technology was presented from three aspects:introducing more factors into classical equations,combining grey system theory models with other methods,obtaining more experimental data,and conducting deep learning and fitting.
