Title:
HYDROPHILIC COATING BASED ON ACRYLIC ACID POLYMERIZATION AND PHOTOCURING, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/040559
Kind Code:
A1
Abstract:
The present invention relates to the technical field of material surface treatment, and disclosed are a hydrophilic coating based on acrylic acid polymerization and photocuring, and a preparation method therefor. The preparation method for a hydrophilic coating in the present invention comprises the following steps: (1) immersing a base material in a pre-treating solution, taking the base material out and drying same to obtain a pre-treated base material; (2) uniformly mixing an acrylic acid monomer, a cross-linking agent, a photoinitiator, a hydrophilic macromolecule, glycerol and water to obtain a hydrophilic solution; and (3) immersing the pre-treated base material obtained in step (1) in the hydrophilic solution obtained in step (2), curing the base material under an ultraviolet lamp while immersion, taking the base material out and cleaning same to obtain a hydrophilic coating-containing base material. The hydrophilic coating of the present invention has excellent bonding strength and hydrophilicity, exhibits an ultra-low friction coefficient in a body fluid environment, is simple in process and has low requirements on an environment and a device.
