Example Embodiment
[0018] The present invention will be further described in detail below: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation manners are given, but the protection scope of the present invention is not limited to the following embodiments.
[0019] The preparation method of a transparent self-adaptive shape memory polymer wrinkle removing body film solution involved in this embodiment includes the following steps: 1. Using DMF (N,N-dimethylformamide) The molecular sieve is dried to obtain dry DMF. The liquid PCL (polycaprolactone) is placed in a reaction vessel and vacuumed for dehydration, and then dried DMF and MDI (diphenylmethane diisocyanate) are added under the protection of argon. Stir and react for 1.5-2.5h at ~80℃ to obtain prepolymer;
[0020] 2. Add 1,4-BDO (1,4-butanediol) and dry DMF to the prepolymer obtained in step 1, and carry out chain extension reaction at 70~80℃ to obtain a solid content of ...
