Magnetic Superhydrophobic Polymer Nanosphere Cage as a Framework for Miceller Catalysis in Biphasic Media
This study demonstrated the use of a magnetic superhydrophobic polymer nanosphere cage derived from a Pickering emulsion as a framework for miceller catalysis in biphasic media. We designed this system through the covalent stabilisation of active site (2,2,6,6-tetramethylpiperidine 1-oxyl)-grafted amphiphiles onto the magnetic hydrophobic core to form a micelle-like architecture and used it as a P...

40. Polymer electrolyte membranes based on cross-linked highly sulfonated co-polyimides
A novel diamine monomer 3,3''''''''-Bis(2,3,5,6-tetrafluoro-4-vinylphenoxy) biphenyl-4,4''''''''-diamine (TFVBPA) bearing double hydrophobic cross-linkable tetrafluorostyrol side-groups has been successfully synthesized via a nucleophilic substitution reaction. A series of cross-linked highly sulfonated co-polyimide (CSPIy-TFVBPAx) membranes with ion-exchange capacity (IEC) values ranging from 2.2...

Bottom-up fabrication of zwitterionic polymer brush on intraocular lens for improved biocompatibility
Intraocular lens (IOL) is an efficient implantable device commonly used for treating cataracts. However, bioadhesion of bacteria or residual lens epithelial cells on the IOL surface after surgery causes postoperative complications, such as endophthalmitis or posterior capsular opacification, and leads to loss of sight again. In the present study, zwitterionic polymer brushes were fabricated...

Thermo-responsive rheological behavior of borinic acid polymer in dilute solution.
In comparison with other boron containing polymers, the investigations on the borinic acid containing polymers have been mostly ignored in spite of their easy synthesis. Our previous studies indicate a borinic acid polymer (PBA) holds promising potential as a new type of stimuli-responsive polymer. However, the property investigations were mainly based on turbidity changes. Here, we report the r...

Properties of Polymer-Modified Mortar Using Silane as an Integral Additive
In the present paper, the addition of silane to improve the properties of mortar was
experimentally investigated. The morphology and microstructure of mortar were
investigated by using both scanning electron microscopy (SEM) and polarizing microscopy
(PM). The results show that silane significantly alters the microstructure of mortar, reduces
the crystallization, restricts the degree...

Studying Polymer Surfaces and Interfaces with Sum Frequency Generation Vibrational Spectroscopy
Usually a surface or an interface is well-defined with little diffusion from one side of the surface or interface to the other, with the length scale being on the order of one to several molecules. The molecular interactions on a surface or at an interface are thus dominated by short-range interactions. Various properties, such as wettability, reactivity, bi...

(Polymer) Electrical Transport and Magnetoresistance in Advanced Polyaniline Nanostructures and Nanocomposites
In this paper, the electrical transport mechanism and giant magnetoresistance (GMR) in advanced polyaniline (PANI) nanostructures and the related PANI nanocomposite systems are critically reviewed. The GMR phenomena in these materials have been theoretically interpreted by numerical models including forward interference model and wave-function shrinkage model. This knowledge...

(Polymer) Magnetoresistive Polyaniline-Magnetite Nanocomposites with Negative Dielectrical Properties
Magnetic polyaniline (PANI) polymer nanocomposites (PNCs) reinforced with magnetite (Fe3O4) nanoparticles (NPs) have been successfully synthesized using a facile surface initiated polymerization (SIP) method. The chemical structures of the PANI/Fe3O4 PNCs are characterized by Fourier transform infrared (FT-IR) spectroscopy. The thermal stability of the PANI/Fe3O4 PNCs is performed ...

[Polym. Chem.] Polymer Brushes on Metal–Organic Frameworks by UV-Induced Photopolymerization
Metal–organic frameworks (MOFs) are extremely promising candidates for application in diverse fields. However, a limitation to the widespread use of MOFs is the absence of a facile and efficient chemical modification method which can greatly improve their poor processability and stability without altering the inherent outstanding chemical and physical properties. Herein, we report a universal pos...

[ Polymer] Electrically conductive thermoplastic polyurethane/polypropylene nanocomposites with selectively distributed graphene
The electrically conductive nanocomposites composing of different concentrations (0.05–1.5 wt%) of reduced graphene oxide (RGO) in the thermoplastic polyurethane/polypropylene (TPU/PP, 55/40) matrix with a fine co-continuous structure were fabricated by solution-flocculation and melt-mixing process using a micron twin-screw extruder. Both thermodynamic and kinetic theoretical analysis predicate...
