    "protocol": "Prepare amphiphilic SIPN coatings from POSS-PDMAEMA-PSBMA block copolymers by integrating POSS with both PDMAEMA and PSBMA via atom transfer radical polymerization (ATRP). Add a small amount (10 wt%) of EGDMA and perform UV-curing.The POSS-PDMAEMA-b-PSBMA block copolymers were synthesized via ATRP of DMAEMA using POSS-Br as an initiator, followed by ATRP of SBMA using POSS-PDMAEMA-Br as a macroinitiator. Three block copolymers with different polymerization degrees (POSS-PDMAEMA50-b-PSBMA7, POSS-PDMAEMA70-b-PSBMA10, and POSS-PDMAEMA90-b-PSBMA13) were prepared. For control, PDMAEMA-b-PSBMA was synthesized using ethyl-2-bromoisobutanoate as the initiator. The block copolymers were characterized by 1H NMR, FTIR, GPC, and TGA. The SIPN coatings were prepared by dissolving the block copolymer in 2,2,2-trifluoroethanol to create a 25 mg/mL solution, adding EGDMA (10 wt% based on copolymer) and Igracure 2959 UV photoinitiator (2 wt%). The solution was cast onto a glass slide and cured under UV light (365 nm, 15 W, 1800 s). The coatings were air-dried at room temperature."
