“…The membranes are made of chitin nanowhiskers arranged in a chitosan matrix. Due to the higher proton conductivity and lower methanol permeability, there is great potential for use as electrolyte membranes in fuel cells [97]. Chitosan combined with silica on quartz crystal microbalance sensors provided better film formation abilities in the composite.…”

Due to the versatility of its features and capabilities, chitosan generated from marine crustacean waste is gaining importance and appeal in a wide variety of applications. It was initially used in pharmaceutical and medical applications due to its antibacterial, biocompatible, and biodegradable properties. However, as the demand for innovative materials with environmentally benign properties has increased, the application range of chitosan has expanded, and it is now used in a variety of everyday applications. The most exciting aspect of the chitosan is its bactericidal properties against pathogens, which are prevalent in contaminated water and cause a variety of human ailments. Apart from antimicrobial and water filtration applications, chitosan is used in dentistry, in water filtration membranes to remove metal ions and some heavy metals from industrial effluents, in microbial fuel cell membranes, and in agriculture to maintain moisture in fruits and leaves. It is also used in skin care products and cosmetics as a moisturizer, in conjunction with fertilizer to boost plant immunity, and as a bi-adhesive for bonding woods and metals. As it has the capacity to increase the life span of food items and raw meat, it is an unavoidable component in food packing and preservation. The numerous applications of chitosan are reviewed in this brief study, as well as the approaches used to incorporate chitosan alongside traditional materials and its effect on the outputs.

“…Fuel cells modified with membranes via proton exchange have been displayed as a promising alternative in eco-friendly energy-related fields. The development of a highly conductive proton membrane is the most important aspect that determines the performance and efficiency of fuel cells [ 160 ]. To degrade chitin anaerobically, Li et al created a microbial fuel cell using Aeromonas hydrophila .…”

Herein, we report recent developments in order to explore chitin and chitosan derivatives for energy-related applications. This review summarizes an introduction to common polysaccharides such as cellulose, chitin or chitosan, and their connection with carbon nanomaterials (CNMs), such as bio-nanocomposites. Furthermore, we present their structural analysis followed by the fabrication of graphene-based nanocomposites. In addition, we demonstrate the role of these chitin- and chitosan-derived nanocomposites for energetic applications, including biosensors, batteries, fuel cells, supercapacitors and solar cell systems. Finally, current limitations and future application perspectives are entailed as well. This study establishes the impact of chitin- and chitosan-generated nanomaterials for potential, unexplored industrial applications.

“…Chitosan has the advantages like low cost, hydrophilicity, biocompatibility, biodegradability, non-toxicity [2,3] make chitosan has widely used in pharmaceutical, medical, food packaging and adsorbent. In contrast to the advantages, chitosan has some disadvantage like pH dependent and low proton conductivity in comparison to Nafion ® due to relatively high degree of crystallinity and lack of mobile protons [4].…”

“…Sulfonation commonly used for polymer modification to increase hydrophilicity and other membrane properties like high water flux and proton conductivity [6]. The sulfonation of chitosan can reduce the crystallinity of chitosan resulting in dramatic changes of mechanical and thermal properties but improve the proton conductivity of chitosan [4,7].…”

The purpose of this study was to synthesis and characterized sulfonated chitosan using acetyl sulfate. Sulfonated chitosan has been successfully synthesized using an alternative sulfonating agent using acetyl sulfate. Sulfonated chitosan was prepared by varying the volume of acetyl sulfate against chitosan for 1 hour at 40 oC and then terminated and filtered to obtain sulfonated chitosan. The sulfonated chitosan was characterized using Fourier Transform Infrared (FTIR), thermal analysis, and cation exchange capacity (CEC). FTIR data showed that all variation of sulfonated chitosan have sulfonate groups attached to both amine and hydroxyl group from chitosan. Thermal analysis showed lower thermal stability of sulfonated chitosan than chitosan. CEC data shows that the highest value obtained 14,5 mmol/g for addition 25 mmol acetyl sulfate. Sulfonated chitosan shows a high value of CEC and it has a promising material for polymer electrolyte membrane in Fuel Cells technology.
