The research progress of the mechanical properties of the coating is introduced, and the test methods and the application of crosslink density are summarized. The existing constitutive model is analyzed and suggestions for improvement are put forward. The mechanical properties of the coating in complex environment is the key point for the next research. Investigating macro mechanical properties of the coating through micro-mechanism analysis is the trend for mechanice analysis. Application of modern instruments like NMR can overcome the shortages of the conventional methods, which prospects a positive future.
