Photocuring is a crosslinking process, widely employed to produce polymers in the form of film. As it an environmentally friendly particularly interesting for preparation sustainable materials and composites. In this work, composite self-standing films were obtained combining microfibrillated cellulose (MFC) photocured matrices. To understand influence polarity surface tension matrix on propert...

Abstract: This paper reports the reaction of cotton cellulose with sulphamic acid using pad bake process. FT-IR and FT-Raman were used to analyse the intermediate products formed during this study. The self-crosslinking of the modified cotton fibre has special characteristics including good dye ability in case of ammonia or ethanolamine initiated crosslinking. Peroxide should react with the mod...

The use of protein crystals as a source of nanoscale biotemplates has attracted growing interest in recent years owing to their inherent internal order. As these crystals are vulnerable to environmental changes, potential applications require their stabilization by chemical crosslinking. We have previously shown that such intermolecular chemical crosslinking reactions occurring within protein c...

Covalently crosslinked polymeric materials which swell, but do not dissolve, in a given solvent (polymer gels) have found utility in a number of applications including tissue engineering, drug delivery, chemical sensing, microfluidics, cosmetics, and microelectronics. End-linked polymer gels (model networks or MNs) are especially promising for drug delivery applications due to their easily cont...

Highly conductive and low vanadium permeable crosslinked sulfonated poly(ether ether ketone) (cSPEEK) membranes were prepared by electrophilic aromatic substitution for a Vanadium/Air Redox Flow Battery (Vanadium/Air-RFB) application. Membranes were synthesized from ethanol solution and crosslinked under different temperatures with 1,4-benzenedimethanol and ZnCl2 via the Friedel-Crafts crosslin...

Poly (vinyl alcohol) membranes were prepared by in-situ crosslinking of poly (vinyl alcohol) with glutaraldehyde as a crosslinking agent and hydrochloric acid as catalyst and the membranes were used to separate mixtures of IPA and water. Effects of feed composition, operating temperature, vacuum pressure and Reynolds number on permeation performance of the membranes were evaluated. The results ...

There is a general interest among paper and board makers to produce lighter and bulkier paper and board products. The aim of the present study was to characterize chemically crosslinked hardwood kraft fibers regarding their potential in making bulky paper and board. Crosslinking agents are molecules that contain two or more reactive ends that form inter-chain covalent bonds with cellulosic hydr...

A kinetic gelation model has been developed that incorporates the kinetics of a living/ controlled radical polymerization. Specifically, the kinetics of an iniferter polymerization were implemented in the model to determine the effect of the kinetics on the polymer structure. In particular, the replacement of the termination step with a reversible termination was examined. The model predicts th...

In determining protein-protein interactions in native muscle membranes biochemically, bifunctional crosslinking agents of various length and solubility have been established as effective tools. Gel electrophoretic and immunoblotting methodology have proven to be highly suitable for the analysis of crosslinked products. Here, we have analysed the oligomeric status of a well established muscle me...
