Spontaneous Approach To Prepare Damping Structural Integration Materials via Gradient Plasticization Mechanism at Nanometer Scale
ABSTRACT: The gradient phenomenon is commonly seen in nature, and the gradual changes in structure could make materials with unique excellent performances compared with homogeneous materials. In this study, a novel approach to prepare damping structural integration epoxy thermosets has been developed. The damping mechanism was systematically discussed through TEM, SAXS, DSC, and DMA. It is shown...

Preparation of damping structural integration materials via the formation of nanostructure in triblock copolymer modified epoxy resins
ABSTRACT: Amphiphilic triblock copolymer Poly(ε-caprolactone)-block-polydimethylsiloxane-block-poly(ε-caprolactone) (PCL-b-PDMS-b-PCL, LDL) was synthesized via the ring-opening polymerization of ε-caprolactone in the presence of hydroxyl-terminated polydimethylsiloxane
(HTPDMS) and was utilized to modify epoxy. The tensile strength and elongation at break were simultaneously enhanced when...

【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 ...

Highly dispersed Zn nanoparticles confined in a nanoporous carbon network: promising anode materials for sodium and potassium ion batteries
Highly dispersed Zn nanoparticles confined in a nanoporous carbon network (ZNP/C) are prepared by directly annealing a Zn-containing metal-organic framework in an inert atmosphere and investigated as an anode material for sodium and potassium ion batteries for the first time. ZNP/C has unique structural features, such as highly dispersed Zn nanoparticles, a nanoporous carbon network and a high s...

【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...

【63 Advanced Materials Interfaces】 Programmable actuation of porous poly(ionic liquid) membranes by aligned carbon nanotubes
A porous composite membrane, combined poly(ionic liquids) with aligned carbon nanotubes that shows anisotropic actuation toward organic solvent is developed. The membrane actuator shows rapid and reversible actuation in response to acetone vapor as well as improved conductivity. These properties allow the composite membrane to be organic solvent‐induced actuator as well as a power switch.
