[ACS Appl. Mater. Interfaces] Engineering Gold Nanoparticles in Compass Shape with Broadly Tunable Plasmon Resonances and High-Performance SERS
We present the uniform and high-yield synthesis of a novel gold nanostructure of compass shape composed of a Au sphere at the central and two gradually thinning
conical tips at opposed poles. The Au compass shapes were synthesized via a
seed-mediated growth approach employing a binary mixture of
cetyltrimethylammonium bromide (CTAB) and sodium oleate (NaOL) as the
structure-directing agent. Under ...

2016-Chem Mater： Improvement of Mechanical Strength and Fatigue Resistance of Double Network Hydrogels by Ionic Coordination Interactions
Double network hydrogels (DN gels) are considered as one of the toughest soft materials. However, conventional chemically linked DN gels often lack high self-recovery and fatigue resistance properties due to permanent damage of covalent bonds upon deformation. Current strategies to improve self-recovery and fatigue resistance properties of tough DN gels mainly focus on the manipulation of the fi...

【Mater Design】Effect of a dual compatibilizer on the formation of co-continuous morphology of immiscible polymer blends
This work aims at investigating the effect of a dual compatibilizer on the formation of co-continuous morphology of immiscible polymer blends. More specifically, the blend is composed of polystyrene (PS) and polyamide 6 (PA6), and the dual compatibilizer is composed of a low molecular weight styrene-co-maleic anhydride copolymer (Mw = 11 500 g/mol, maleic anhydride MAH content = 14 wt.%) denoted a...

【J. Mater. Chem. C】A direct microcontact printing induced supramolecular interaction for creating shape-tunable patterned polymeric surfaces
Multifunctional patterned polymeric surfaces are of significant importance to numerous surface-based researches. We demonstrated that a commercial polymer of polyethylenimine (PEI) with rich amino groups can be used as a versatile ink for the direct fabrication of patterned PEI surfaces via a supramolecular interaction between amino groups in PEI and -OH on a silicon wafer induced by microcontact ...

【ACS Appl. Mater. Interfaces】Gold Nanowire Bundles Grown Radially Outward from Silicon Micropillars
One-dimensional (1D) micro- and nanostructures have become increasingly popular because of their tremendous prospect in various applications. While the design and fabrication of these structures from a single component in two-dimensional (2D) arrays is common, the attainment of hierarchical three-dimensional (3D) architectures made up of multicomponent one-dimensional st...

【J. Mater. Chem. A】Controlled functionalization of carbon nanotubes as superhydrophobic material for adjustable oil/water separation
A robust strategy for fabricating superhydrophobic carbon nanotube (CNT)-based hybrid materials as a separation membrane through the covalent attachment of the fluorine-bearing organosilane 1H,1H,2H,2H perfluorodecyltriethoxysilane (PFDTS) onto -OH functionalized CNTs is proposed. This method resulted in PFDTS/CNT superhydrophobic materials with controlled functionalization that could be used to e...

【ACS Appl. Mater. Interfaces】Janus Polymer/Carbon Nanotube Hybrid Membranes for Oil/Water Separation
A robust and simple method is provided to fabricate Janus polymer/carbon
nanotube (CNT) hybrid membranes for oil/water separation. Starting from CNT
membranes formed by dispensing, hydrophobic poly(styrene) (PS) and hydrophilic
poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) were grated from different
sides of the photoactive CNT membranes via self-initiated photografting and
...

【J. Mater. Chem. C】Evidence of concerted inversion for the photon-induced molecular switching of azobenzene using rotation-free azobenzene derivatives
The excited state relaxation of two types of azobenzene derivative excited at 350 nm in the short-wavelength (S2([small pi], [small pi]*)) band was studied by transient absorption spectroscopy. We compared the relaxation dynamics and the time-resolved anisotropic relaxation properties of these two molecules in liquid solution and in bulk film. The average relaxation life-time for Azo-2 in bulk fil...

【ACS Appl. Mater. Interfaces】Fluorescent pH Sensor Based on Ag@SiO2 Core–Shell Nanoparticle
We have demonstrated a novel method for the preparation of a fluorescence-based pH sensor by combining the plasmon resonance band of Ag core and pH sensitive dye (HPTS). A thickness-variable silica shell is placed between Ag core and HPTS dye to achieve the maximum fluorescence enhancement. At the shell thickness of 8 nm, the fluorescence intensity increases 4 and ...

【ACS Appl Mater Interfaces】Facile Fabrication of Lubricant-Infused Wrinkling Surface for Preventing Thrombus Formation and Infection
Despite the advanced modern biotechniques, thrombosis and bacterial infection of biomedical devices remain common complications that are associated with morbidity and mortality. Most antifouling surfaces are in solid form and cannot simultaneously fulfill the requirements for antithrombosis and antibacterial efficacy. In this work, we present a facile strategy to fabricate a slippery surface. This...
