Enhanced interfacial adhesion between polypropylene and carbon fiber by graphene oxide/polyethyleneimine coating
In order to improve the interfacial properties in polypropylene/carbon fiber (PP/CF) composites, graphene oxide and brached polyethyleneimine were coated onto the surface of carbon fiber by layer-bylayer assembly in this work. Compared with the origin PP/CF composite, the composites reinforced by PP/CF–GO showed significant enhancement not only in tensile strength but also in elongation at brea...

In Vivo Anti-Biofilm and Anti-Bacterial Non-Leachable Coating Thermally Polymerized on Cylindrical Catheter
Catheters are indispensable tools of modern medicine, but catheterassociated infection is a significant clinical problem, even when stringent sterile protocols are observed. When the bacteria colonize catheter surfaces, they tend to form biofilms making them hard to treat with conventional antibiotics. Hence, there is a great need for inherently antifouling and antibacterial catheters that preve...

【ACS Applied Materials & Interfaces】Water-insoluble polymeric guanidine derivative and application in the preparation of antibacterial coating of catheter
Abstract:
Antibacterial coatings have been considered as an effective method for preventing the implant-associated infections caused by the bacterial colonization. In this study, we report a water-insoluble polyelectrolyte–surfactant complex, poly(hexamethylene biguanide) hydrochloride–sodium stearate (PHMB–SS) that can be facilely coated onto the surfaces of biomedical catheter and ...

【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...

[Adv. Mater.] One-Step Assembly of a Biomimetic Biopolymer Coating for Particle Surface Engineering
Advances in material design and applications are highly dependent on the development of particle surface engineering strategies. However, few universal methods can functionalize particles of different compositions, sizes, shapes, and structures. We describe the amyloid-like protein assembly-mediated surface modification and functionalization of particles and living colloids with different compos...

Fabrication of dissolving microneedles with thermal-responsive coating for NIR-triggered transdermal delivery of metformin on diabetic rats
ABSTRACT: This study described a near-infrared (NIR) light-responsive polymer-nanodots composite microneedles (MNs) used for on-demand transdermal drug delivery. Bismuth (Bi) nanodots stabilized by poly(vinylpyrrolidone) (PVP) as photothermal conversion agent and metformin as anti-diabetic drug were introduced into the dissolving MNs that coated with lauric acid (LA). When the MNs were irrad...

Paper Sensor Coated with a Poly(carboxybetaine)-Multiple DOPA Conjugate via Dip-Coating for Biosensing in Complex Media
Cellulose paper is an ideal diagnostic platform for low-cost, easily disposable and lightweight implementation, but requires surface modification to achieve detection with high sensitivity and specificity in complex media. In this work, a polymer-catechol conjugate containing a superhydrophilic nonfouling poly(carboxylbetaine) (pCB) and four surfacebinding L-3,4-dihydroxyphenylalanine (DOPA) gro...

Durable antibacterial and nonfouling cotton textiles with enhanced comfort via zwitterionic sulfopropylbetaine coating.
We report a rapid,
environment-friendly, and costeffective fi nishing method for cotton textiles
by using the isocyanate-coupled sulfopropylbetaine (NCO-sulfopropylbetaine) as
the AFA through covalent bond. The sulfopropylbetaine-fi nished cotton textile
performs the following functions: (i) resists initial bacterial
attachment; (ii) kills attached bacteria; and (iii) releases dead bacter...
