Fabrication of quantum dots-encoded microbeads with a simple capillary fluidic device and their application for biomolecule detection
Monodispersed quantum dots (QDs)-encoded polymer microbeads were generated using a simple capillary fluidic device (CFD). The polymer and QDs solution was emulsified into monodispersed microdroplets by the CFD and obtained droplets were solidified via solvent evaporation. Polymer microbeads can be fabricated in a range of different sizes through changing the flow rates of the two immiscible phases...

Preparation of poly(p-styrenesulfonic acid) grafted multi-walled carbon nanotubes and their application as a solid-acid catalyst
Poly(p-styenesulfonate acid)-grafted multi-walled carbon nanotubes (PSSA-g-MWCNTs) were prepared by in situ polymerization of sodium p-styrenesulfonate in the presence of MWCNTs, followed by refluxing with concentrated hydrochloric acid. In this reaction system, sodium p-styrenesulfonate served not only as the reaction monomer but also as an amphiphilic dispersant to disperse pristine MWCNTs in wa...

Surface Modification of Hydrophobic PMMA Intraocular Lens by the Immobilization of Hydroxyethyl Methacrylate for Improving Application in Ophthalmology
To improve application of hydrophobic polymethyl methacrylate intraocular
lens (PMMA IOL) in a convenient and continuous way, 2-hydroxyethyl methacrylate
(HEMA) was immobilized by dielectric barrier discharge plasma at relatively high pressure. The hydrophilicity and topography of the modified IOL surface were comprehensively evaluated by contact angle and atomic force microscopy, while the surf...

Water-Soluble Starlike Poly(acrylic acid) Graft Polymer: Preparation and Application as Templates for Silver Nanoclusters
Water-soluble starlike polymers containing concentrated carboxyl groups were conveniently synthesized via the combination of “click” chemistry and atom transfer radical polymerization (ATRP). The starlike polymer was composed of a shorter polyacrylate main chain and longer poly(acrylic acid) side chains. Alkyne and azide groups were introduced to the structure units of the main chain b...

Fabry-Perot Fringes and Their Application to Study the Film Growth, Chain Rearrangement and Erosion of Hydrogen-Bonded PVPON/PAA Films
We observed Fabry-Perot fringes in the absorption spectra of hydrogen-bonded layer-by-layer (LBL) films of poly(vinyl pyrrolidone) (PVPON) and poly(acrylic acid) (PAA), which stem from the interferences between beams transmitted and partially reflected at the highly smooth film-air interface and film-quartz interface. The appearance and disappearance of Fabry-Perot fringes can be used to evaluate ...

Interaction of Sulfonated Calixarenes with Rhodamine B and its Application to Determine Acetylcholine in a Real Neutral Aqueous Medium
Complexation between Rhodamine B (RB) and sulfonated calix [n] arenes ( SCnA) were studied by means of UV-vis spectroscopy and fluorescence spectroscopy. In the presence of sulfonated calix [n] arenes, the absorption band of Rhodamine B shifts to longer wavelength and its intensity decreases. The formation of a host-guest type complex also results in the fluorescence quenching of Rhodamine B...

A facile one-step synthesis to ionic liquids-based cross-linked polymeric nanoparticles and their application for CO2 fixation
Highly cross-linked polymeric nanoparticles (CLPN) were prepared via a facile one-step synthesis. These nanoparticles are effective catalyst for CO2 cycloaddition to epoxides. In this study, CLPN was synthesized by radical copolymerization of 4-vinylbenzyl-tributylphosphorous chloride (PIL) and ethylene glycol dimethacrylate (EGDMA) in selective solvent, such as C1~C5 alcohols. The results reveale...

Preparation of Layered Double Hydroxide Wrapped Carbon Nanotubes and its application as a flame retardant for polypropylene
Carbon nanotubes wrapped with layered double hydroxide (LDH-w-CNTs) was facilely obtained through in-situ introducing CNTs into the hydrothermal reaction system of LDH, with the goal of combining their unique physical and chemical characteristics to meet new advanced applications. Morphology observation indicated that LDH lamella enwrapped on the surface of CNTs and the wrapping degree was depende...
