Aqueous broadband photopolymerization on microreactor arrays: from high throughput polymerization to fabricating artificial cells

Abstract

Photopolymerization is attracting great attention due to its advantages such as low cost and spatiotemporal control. Broadband photopolymerization is attractive than ultraviolet polymerization, which is of special significance for better...

Graft Polymerization of Stearyl Methacrylate on PET Track-Etched Membranes for Oil–Water Separation

“…Since the radiation energy is low, grafting takes place under mild conditions and at low temperatures. Photoinitiated graft polymerization is widely used to modify the surface of various polymers, and it is based on the formation of radicals on the polymer surface with the help of photoinitiators that generate radicals under UV irradiation or sensitizers that are capable of abstracting a hydrogen atom from the polymer chain, and then the formed radicals initiate polymer chain growth from the surface [ 24 , 25 ].…”

Photocontrolled RAFT polymerization: past, present, and future

“…152 It has to be noted that categorizing these reports which harnessed amine additives as photoiniferter polymerization might be controversial because herein amine-catalyzed electron transfer instead of the direct photolysis of the CTA initiated the polymerization, which was similar to PC-catalyzed electron transfer in PET-RAFT polymerization. Meanwhile, Chen and coworkers introduced Zn 0.64 Fe 2.36 O 4 into DMSO 154,155 or ZnO NPs into aqueous medium 156 to reduce oxygen to a hydroxyl radical via photoinduced generation of electron-hole pairs under sunlight irradiation, and enabled open-to-air photoiniferter polymerization from various CTAs despite the poor controllability (Ð = 1.35-1.56).…”

In situ PET-RAFT polymerization to prepare guanidine-and-carbohydrate modified ZnO nanoparticles

“…19,20 Previously, we have successfully employed the photocatalytic properties of ZnO NPs to perform high throughput PET-RAFT polymerization in aqueous media. 21 Among antibacterial polymers that are not prone to drug resistance, guanidine polymers are a good choice with certain advantages: the guanidine group can be ionized in a wider pH range, and it can bind to the cell membrane in the form of dihydro bonds, making the bacterial cell membrane firmly bound and the antibacterial ability stronger. 22 Carbohydrates play a significant role in biological processes such as recognition and signaling, [23][24][25][26][27] and they have a high affinity for proteins, making them suitable for applications that require target-specific binding.…”
