    "protocol": "To synthesize hydrophilic polymers with functional groups, the following materials are used: TPGDA, NPG(PO)2DA, TMPTA, TMP(EO)3TA, GP(PO)3TA, PE-TIA, DPHA, EBECRYL series of di-, tri-, tetra-, and hexafunctional urethane and polyester acrylates, and SR502. The process involves high-speed stirring using an SFJ-400 mixer. UV curing is performed using a conveyor UV curing machine from IST, followed by measuring the coating thickness with a Qnix 4500 device. A photo initiator, IRGACURE 184, is utilized during the synthesis.按照表 1 依次配料， 然后用高速搅拌机在800~r/min 的条件下搅拌 15~min， 密封避光存放。将配好的涂料依次喷于 ABS 板上，置于烘箱闪干，然后通过履带式 UV 固化机固化。漆膜厚度控制在 $10\\sim15~{\\upmu\\mathrm{m}}$。"
