“…Chitosan as a natural polymer also has the potential to be developed as an electrolyte membrane for fuel cells because it is a plantbased material abundant in nature. Some of the advantages of chitosan as an electrolyte membrane are (a) cheap and environmental-friendly, (b) hydrophilic and capable of operating at high temperature, (c) low methanol permeability, and (d) the backbone of chitosan has a functional group making it is easier to modify [12]. This natural polymer has already been widely used in the pharmaceutical field, separation technology, and water treatment.…”

“…This natural polymer has already been widely used in the pharmaceutical field, separation technology, and water treatment. Recently, chitosan attracts attention for its use as a proton exchange membrane material because of its unique properties, such as hydrophilic, good thermo-chemical stability, easily modified, low methanol permeability, and reasonable price [12,13].…”

Abstract. Direct Methanol Fuel Cell (DMFC) is fuel cell that converts directly chemical energy in methanol into electrical energy and can be used as a power source for portable electric devices. Compared to Proton Exchange Membrane Fuel Cells (PEMFCs) which use hydrogen as the fuel, DMFC has some advantages, yet methanol-crossover remains a challenge to be solved. In this study, Acrylonitrile Butadiene Styrene (ABS) and chitosan were blended and their characteristics as membrane for DMFC were evaluated. Membranes with variation of chitosan and ABS mass ratio (60:40 and 80:20) and sulfonation time (6, 12, 18, and 24 hours) were prepared and the characteristics such as water uptake, swelling degree, ion exchange capacity and methanol permeability were determined. Both chitosan and ABS mass ratio and time of sulfonation influence the investigated responses. As a result, blended chitosan and ABS is feasible as the DMFC membrane.

“…Therefore, natural polymer chitosan (CS) and synthetic polymer poly(vinyl alcohol) (PVAL) have drawn considerable attention. [3][4][5][6] CS is the second most abundant natural biopolymer obtained by chitin alkaline deacetylation. Due to its low cost production, natural abundance and eco-compatibility, CS is the preferred bio-material membrane for ultra-filtration, reverse-osmosis and pervaporation.…”

“…Due to its low cost production, natural abundance and eco-compatibility, CS is the preferred bio-material membrane for ultra-filtration, reverse-osmosis and pervaporation. 3,7,8 PVAL is also an attractive material for membrane electrolyte development as it is a cheap polymer holding high density functional -OH groups with potential for chemical crosslinking. [9][10][11] These polymers show good film forming properties, chemical resistance and the hydrophilic group high density allows chemical modifications of the polymer chain by crosslinking and grafting.…”

Membranes for fuel cell applications were prepared using two polymer blends: poly(vinyl alcohol) (PVAL) and chitosan (CS), 80/20 (w/w) and 60/40 (w/w) with and without nylon. Sulfosuccinic acid (SSA) was used both as a crosslinking and a sulfonating agent. An increasing in the SSA content raised ionic exchange capacity and consequently proton conductivity in the membranes. The addition of nylon has improved membrane mechanical properties by decreasing stiffness. Membranes presented good proton conductivity (around 10 -2 S cm -1 ) and lower H 2 and methanol permeability rather than the standard membrane Nafion ® 115. Membranes which showed to be stable under fuel cell operation were tested using hydrogen and methanol fuels. Membrane PVAL:CS, 80/20 (w/w), containing SSA crosslinker, (PVAL+CS)/SSA, of 4/1 (mol/mol), has shown the best performance under fuel cell environment. However, results have shown that an improvement is required in the adhesion between the membrane and the electrodes.

“…For instances, chitosan was extensively investigated in metal extraction [2][3][4], chemical synthesis reaction [5,6] and electrolyte-based fuel cells studies [7,8]. Chitosan was explored to be a mild and direct solid catalyst in organic synthesis without any post-modification [6,9,10].…”

Chitosan as a Natural Polymer for Heterogeneous Catalysts Support: A Short Review on Its Applications

2015

View full text Add to dashboard Cite

Chitosan, a bio-based polymer which has similar characteristics to those of cellulose, exhibits cationic behavior in acidic solutions and strong affinity for metals ions. Thus, it has received increased attention for the preparation of heterogeneous catalysts. Recent studies demonstrated that chitosan-based catalysts had high sorption capacities, chelating activities, stability and versatility, which could be potentially applied as green reactants in various scientific and engineering applications. This study intends to review the recent development of chitosan-based catalysts, particularly in the aspects of the main mechanisms for preparing the materials and their applications in environmental green chemistry. Studies on the preparation of catalyst nanoparticles/nanospheres supported on chitosan were also reviewed.
