Introduction Implantation of intraocular lens (IOL) in cataract surgery may lead to infectious endophthalmitis which is the most feared and common complication 1 2 Despite the enormous progress made in asepsis microsurgical techniques suture materials prosthetic materials and antibiotics postoperative endophthalmitis continues to be a great threat to ophthalmology patient vision 3 The Hydrophilic poly((poly(ethylene glycol) methyl ether methacrylate) (P(PEGMA)) brushes were grafted from chloromethylated polyethersulfone (CMPES) hollow fiber membrane surface by surface-initiated atom transfer radical polymerization(SI-ATRP) to improve the membrane's hydrophilic property The CMPES hollow fiber membrane was prepared by phase inversion process

First controlled surface-initiated polymerizations required the development of a number of controlled polymerization techniques in particular those based on radical chemistry such as atom-transfer radical polymerization (ATRP) reversible addition–fragmentation chain-transfer (RAFT) polymerization nitroxide-mediated polymerization (NMP

3 2 Surface-Initiated ATRP of P[(t-BA)-stat-PEGMA] Copolymers on MNPBTPAm immobilized on the particle surface was thought to be able to trigger ATRP reaction Because the polymers grafted on the particle surface were not detectable via an NMR technique due to inherent magnetic properties of MNP utilization of EBiB as a "sacial initiator" was employed to monitor the reaction progress

The POEGMA brush of 48 3 nm in thickness is prepared via surface-initiated atom transfer radical polymerization method Field-emission scanning electron microscope and Raman measurements indicate that silver nanoparticles of 14 ∼ 25 nm in diameter are successfully embedded into the POEGMA brush
