【Journal of Materials Chemistry B】Bacterial adaptability of enzyme and pH dual-responsive surface for infection resistance
Abstract:
A major challenge in antibacterial surface preparation is the elaborated implementation of controlled antibacterial agent delivery on demand, typically at appropriate concentrations and sites, which can be an efficient way to lower bacteria resistance and improve therapy effectiveness. Herein, we present a bacterial hyaluronidase (HAase) and pH dual-responsive antimicrobial surface,...

Synthesis and characterization of well-defined PAA–PEG multi-responsive hydrogels by ATRP and click chemistry
Multi-responsive poly(acrylic acid)–poly(ethylene glycol) (PAA–PEG) hydrogels with well-defined crosslinking structures were synthesized using atom transfer radical polymerization (ATRP) and coppercatalyzed 1,3-dipolar azide-alkyne cycloaddition (CuAAC) techniques. The well-defined PAA–PEG hydrogels with different degrees of crosslinking were produced from controlling the molecular weight of ...

Click-chemistry approach for graphene modification: effective reinforcement of UV-curable functionalized graphene/polyurethane acrylate nanocomposites
This work presents an effective method of preparing graphene reinforced UV-curable materials. Octamercaptopropyl polyhedral oligomeric silsesquioxane (OMP-POSS) functionalized reduced graphene oxide (FRGO) was prepared through a thiol-ene click approach and the FRGO/polyurethane acrylate (PUA) nanocomposite was fabricated by UV irradiation technology. The results of transmission electron microscop...

【Polymer Chemistry】A pH and redox dual responsive homopolypeptide: synthesis, characterization, and application in "smart" single-walled carbon nanotube dispersion
Abstract:
A homopolypeptide, namely poly(S-(2-carboxylethyl)-L-cysteine) (PCELC), with pH and redox dual responsiveness was prepared by ring-opening polymerization of S-(2-(methoxycarbonyl)ethyl)-L-cysteine based N-carboxyanhydride (MCELC-NCA) and subsequent hydrolysis. The pH-induced solution phase transition of PCELC was at pH = ～4.50 as revealed by DLS and UV-vis spectroscopy. The th...

【Journal of Materials Chemistry B-2018年春季】Recent developments in smart antibacterial surfaces to inhibit biofilm formation and bacterial infections
Since their development over 70 years, antibiotics are still the most effective strategy to treat bacterial biofilms and infections. However, the overuse of antibiotics in human healthcare and industrial applications has resulted in the development of serious antibiotic-resistant bacteria. Therefore, alternative ways to prevent bacteria attachment and biofilm formation are urgentl...

【Journal of Materials Chemistry B-2015年春季】Hydrated polysaccharide multilayer as an intraocular lens surface coating for biocompatibility improvements
Posterior capsule opacification (PCO) is a significant complication of intraocular lens (IOL) implantation in cataract surgery, in which the adhesion and proliferation of lens epithelial cells (LECs) on the IOL surface play important roles. In the present study, a highly swollen hyaluronic acid (HA)/chitosan (CHI) polyelectrolyte multilayer was fabricated on the IOL surface via th...

【02 Journal of Materials Chemistry 】Catalyzing carbonization of poly(L-lactide) by nanosized carbon black combined with Ni2O3 for improving flame retardancy
Catalyzing the carbonization of a polymer itself to form a protective carbonaceous layer has attracted tremendous interest in the flame retardancy of polymers, but the efficiency of this strategy was largely limited to polymers containing heteroatoms within their backbone. In this study, a novel type of combined catalyst, consisting of nanosized carbon black (CB) and Ni2O3, was found to efficientl...

【62 Macromolecular Chemistry and Physics】 Main-chain polyimidazolium polymers by one-pot synthesis and application as nitrogen-doped carbon precursors
This paper reports on the one‐pot synthesis of main‐chain imidazolium‐containing polymers, some of which show unusually high thermal stability. The imidazolium polymers are obtained by modified Debus–Radziszewski reactions for the chain build‐up from simple organic compounds, here pyruvaldehyde, formaldehyde, acetic acid, and a variety of diamines. The reactions are performed in aqueous media...

【51 RSC Advances】 Impact of particle surface chemistry on the structure and rheological properties of graphene-based particle/polydimethylsiloxane composites
The structure and rheological properties of graphene-based particle (GP-x)/polydimethylsiloxane (PDMS) composites are investigated as the surface oxygen content of graphene-based particle is varied, i.e., from 6.6% (GP-1) to 15.3% (GP-2), 25.5% (GP-3) and 43.1% (GP-4). Interestingly, the dispersion state of graphene-based particles in PDMS does not change monotonically with increasing surface oxyg...

【55 New Journal of Chemistry】 New insights into the role of lattice oxygen in the catalytic carbonization of polypropylene into high value-added carbon nanomaterials
Catalytic conversion of waste plastics into high value-added carbon nanomaterials (CNMs) has attracted increasing attention; however, the role of lattice oxygen in the carbonization of plastics still remains ambiguous. In this work, firstly, a nickel catalyst with different content of lattice oxygen was prepared by the sol–gel combustion synthesis method. Subsequently, the effect of lattice oxyge...
