Embodiment 1
[0024] Example 1 Select m-dibenzyl mercaptan and butyl methacrylate, which are capable of photoclick reaction, as mercapto monomers and acrylate monomers, and weigh 17.029g and 28.44g respectively. Dissolve the weighed medicine in 100 ml of absolute ethanol at the same time, stir it magnetically for 2 hours until fully mixed, and then set aside for later use.
[0025] Then 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO) was selected as the photoinitiator and 10% of the total mass of the mixture was weighed. Place the weighed photoinitiator into the fully mixed mixture of mercapto monomers and acrylate monomers again, and magnetically stir in a light-shielding bottle until a homogeneous phase is formed. The obtained polymerizable mixture was stored in the dark.
[0026] The polymerizable mixture is evenly coated on the polyethylene plastic film, and after being irradiated by UV light, a photoclick polymerization reaction can be initiated, and then the mixture can be parti...
Embodiment 2
[0030] 1,4-Benzene dimethyl mercaptan and 2-phenoxyethyl methacrylate, which can undergo optical click reaction, were selected as mercapto monomers and acrylate monomers, and 34.058 g and 82.496 g were weighed, respectively. Dissolve the weighed medicine in 150 ml of absolute ethanol at the same time, stir magnetically for 2 hours until fully mixed, and then set aside for later use.
[0031] Then 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO) was selected as the photoinitiator and 15% of the total mass of the mixture was weighed. Place the weighed photoinitiator into the fully mixed mixture of mercapto monomers and acrylate monomers again, and magnetically stir in a light-shielding bottle until a homogeneous phase is formed. The obtained polymerizable mixture was stored in the dark.
[0032] The polymerizable mixture is uniformly coated on the polyester film, and after being irradiated by UV light, a photoclick polymerization reaction can be initiated, and then the mixt...
Embodiment 3
[0035] 1,4-Benzyldimethylmercaptan and benzyl 2-propylacrylate, which can undergo optical click reaction, were selected as mercapto monomer and acrylate monomer respectively, and 34.058g and 81.704g were weighed respectively. Dissolve the weighed medicine in 150 ml of absolute ethanol at the same time, stir magnetically for 2 hours until fully mixed, and then set aside for later use.
[0036] Then 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO) was selected as the photoinitiator and 20% of the total mass of the mixture was weighed. Place the weighed photoinitiator into the fully mixed mixture of mercapto monomers and acrylate monomers again, and magnetically stir in a light-shielding bottle until a homogeneous phase is formed. The obtained polymerizable mixture was stored in the dark.
[0037] The polymerizable mixture is uniformly coated on the polyester film, and after being irradiated by UV light, a photoclick polymerization reaction can be initiated, and then the mix...
