Chemical and morphological properties were evaluated in order to determine the effect of the coatings on the chemical structure, surface hydrophobicity and barrier properties.

The investigation was devoted to elaboration of effective carriers of biological active substrate based on natural tannins, namely, Enoxil. Several types of carriers based on silica or biocompatible. Chitosan is a partially deacetylated derivative of chitin, a natural polysaccharide extracted from crustaceans, insects and certain fungi. Owing to its unique properties such as biodegradability, biocompatability, biological activity, and capacity of forming polyel- ectrolyte complex with anionic polyelectrolytes, chitosan has been widely applied in the food and cosmetics industry as well as 3/5(2).

CO2 separation was found to be facilitated by transport membranes based on novel chitosan (CS)–poly(styrene) (PS) and chitosan (CS)–poly(acrylonitrile) (PAN) copolymer matrices doped with methylimidazolium based ionic liquids: [bmim][BF4], [bmim][PF6], and [bmim][Tf2N] (IL).

CS plays the role of biodegradable film former and selectivity promoter. Copolymers were prepared implementing the Cited by: The miscibility of carboxymethyl chitosan/polyethylenimine (CMCS/PEI) blends was analyzed by FT-IR, TGA and SEM.

Defect-free CMCS/PEI blend membranes were prepared with polysulfone (PSf) ultrafiltration membranes as support layer for the separation of CO2/N2 mixtures. The results demonstrate that the CMCS/PEI blend is miscible, due to the hydrogen bonding interaction between Cited by: Hence, the use of chitosan-based membranes in wastewater treatment is a fast-emerging field of interest to environmental consultants and public interest groups.

This chapter reviews the various preparation and characterization methods for these nanocomposites, their properties, and their by: 2. Due to their morphology, asymmetric membranes have a lower overall membrane resistance in comparison to the symmetric type.

AbstractToday, the need of replacing synthetic polymers in the membrane preparation for diverse pervaporation (PV) applications has been recognized collectively and scientifically. Chitosan (CS), a bio-polymer, has been studied and proposed to achieve this goal especially in specific azeotropic water-organic, organic-water, and organic-organic separations, as well as in assisting specific.

Nafion membranes were modified by chemical polymerization of aniline using ammonium peroxodisulfate as the oxidant. The Nafion−polyaniline composite membranes were extensively characterized using scanning electron microscopy (SEM), atomic force microscopy (AFM), infrared (FTIR-ATR) and X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), differential scanning calorimetry Cited by: This book highlights the various types of polymer and nanocomposites that can be derived from biorenewable resources.

We prepared and characterized a series of semi-IPN (semi-interpenetrating polymer network) membranes based on SPISX–EP (sulfonated polyimide-siloxane and epoxy) polymers and compared their properties with those of a pure SPISX membrane and a commercially available proton exchange membrane.

Overall, the SPISX5–EP (with 5 wt% PDMS (α,ω. We provide a phenomenological description of proton conductance in polymer electrolyte membranes, based on contemporary views of proton transfer processes in condensed media and a model for heterogeneous polymer electrolyte membrane structure.

The description combines the proton transfer events in a single pore with the total pore−network performance and, thereby, relates structural and Cited by: The preparation of carbon membranes by blending materials has many advantages including time and cost effectiveness for tuning the properties of the membranes.

Here we review the recent research progress that has been made in the context of breakthroughs and challenges in the development of carbon membrane materials. Nanocomposites of chitosan and graphene oxide are prepared by simple self-assembly of both components in aqueous media.

It is observed that graphene oxide is dispersed on a molecular scale in the chitosan matrix and some interactions occur between chitosan matrix and graphene oxide sheets.

These are responsible for efficient load transfer between the nanofiller graphene and chitosan by: This work was focused on analyzing the effect produced by the addition of tannic acid as a crosslinking agent of chitosan matrix and the influence of the heat treatment applied.

Taking into account those aspects relevant for packaging applications, thermal stability, mechanical properties, water resistance and kinetics of biodegradation of the film were monitored. Preparation of asymmetric n-HA/CS membranes. According to the reference [] we synthesized n-HA slurry at atmospheric pressure, then adjusted n-HA slurry to neutral.
