We report a new macromolecular architecture of dual functional block copolymer brushes on commercial thin-film composite (TFC) membranes for integrated "defending" and "attacking" strategies against biofouling. Mussel-inspired catechol chemistry is used convenient immobilization initiator molecules to the membrane surface with aid polydopamine (PDA). Zwitterionic polymer strong hydration capacity quaternary ammonium salt (QAS) bactericidal ability are sequentially grafted TFC via activators...
Developing facile and robust technologies for effective enrichment of uranium from seawater is great significance resource sustainability environmental safety. By exploiting mussel-inspired polydopamine (PDA) chemistry, diverse types PDA-functionalized sorbents including magnetic nanoparticle (MNP), ordered mesoporous carbon (OMC), glass fiber carpet (GFC) were synthesized. The PDA functional layers with abundant catechol amine/imine groups provided an excellent platform binding to uranium....
A key challenge of photoregulated living radical polymerization is developing efficient and robust photocatalysts. Now carbon dots (CDs) have been exploited for the first time as metal-free photocatalysts visible-light-regulated reversible addition-fragmentation chain-transfer (RAFT) polymerization. Screening diverse heteroatom-doped CDs suggested that P- S-doped were effective RAFT under mild visible light following a photoinduced electron transfer (PET) involved oxidative quenching...
Azo polymer brushes (G-PCN) on graphene nanosheets are prepared through a "grafting-from" approach. The effect of the photoinduced surface modulation is investigated by irradiating solid films azo molecular glass (Tr-Az-CN) containing with interfering Ar+ laser beams. By formation surface-relief grating, very significant increase in growth rate and saturated value diffraction efficiency observed for Tr-Az-CN doped G-PCN at low content (0.5 wt%). Detailed facts importance to specialist...
Surface-initiated activators regenerated by electron transfer atom radical polymerization (ARGET ATRP) integrated with mussel-inspired polydopamine (PDA) chemistry was, for the first time, employed controlled grafting of poly(glycidyl methacrylate) (PGMA) brushes from carbon nanotubes (CNTs). The strategy initially involved deposition a PDA layer spontaneous self-polymerization, which is benign and nonsurface specific way anchoring 2-bromoisobutyryl bromide to form initiators on CNTs. Dense...
The removal and separation of uranium from aqueous solutions are quite important for resource reclamation environmental protection. Being one the most effective techniques metal separation, adsorption by a variety adsorbent materials has been subject study with high interest in recent years. However, current methods monitoring process require complicated procedures tedious measurements, which hinders development processes efficient uranium. In this work, we prepared type luminescent...
Developing efficient adsorbents for uranium enrichment is of great significance resource sustainability and environmental safety. This study presents a facile adaptable post-synthetic strategy to prepare highly via engineering the π-conjugated skeletons homocoupled conjugated microporous polymers (HCMPs). Taking advantage diyne units in skeletons, bis-amidoxime uranophiles, one state-of-the-art ligands uranyl ions, were introduced frameworks HCMPs. The functionalized HCMPs preserved...

Abstract Graphene oxide (GO) membranes with unique nanolayer structure have demonstrated excellent separation capability based on their size‐selective effect, but there are few reports achieving ion–ion separation, because it is difficult to inhibit the swelling effect of GO nano sheets as well precisely control interlayer spacing d a specific value between sizes different metal ions. Here, selective uranium from acidic radioactive waste containing multication achieved through precise...
