Polymer nanofilms with enhanced microporosity by interfacial polymerization

Inexpensive polyphenylene network polymers with enhanced microporosity

Greatly enhanced microporosity is obtained for the amorphous porous polymers produced from the AlCl3-mediated coupling of aromatic hydrocarbons by using dichloromethane as the reaction solvent. A polymer of average BET surface area 1⁄4 2435 m g 1 was obtained reproducibly from 1,3,5-triphenylbenzene with the additional porosity being provided as ultramicroporosity as demonstrated by very high C...

The Effect of Polymer Surface Modification Via Interfacial Polymerization on Polymer–Protein Interaction

Membrane separation is an important processing technology used for separating food ingredients and fractionating value-added components from food processing byproducts. Long-term performance of polymeric membranes in food protein processing is impeded by the formation of fouled layers on the membrane surface as a result of protein adsorption onto the membrane surface. Surface modification of sy...

Stabilizing interfacial micellar aggregates by enhanced supramolecular interaction or surface polymerization*

This presentation describes the surface micelles formed by self-organization of amphiphilic molecules at the solid/liquid interface, and reviews the methods of stabilizing the surface micelles by enhancing the intermolecular interaction or introducing covalent bonds in self-assemblies. This type of work may provide new avenues for fabricating organic nanostructure materials, as well as possible...

Hybrid polymer photonic crystal fiber with integrated chalcogenide glass nanofilms

The combination of chalcogenide glasses with polymer photonic crystal fibers (PCFs) is a difficult and challenging task due to their different thermo-mechanical material properties. Here we report the first experimental realization of a hybrid polymer-chalcogenide PCF with integrated As2S3 glass nanofilms at the inner surface of the air-channels of a poly-methyl-methacrylate (PMMA) PCF. The int...
