“…The hydroxyl groups in polymer chains are responsible for establishing the bond with the ionic species in the electrolyte, which subsequently contributes to the ionic conductivity [121][122][123]. Furthermore, the functional groups on the polymer chain play an essential role in creating the bond with the liquid as a dispersed phase in the gelation process [124].…”

“…263 ) carrageenan. 351,352 It is water solubility and gelation properties promote its wide application in food and pharmaceutical industries. 353,354 Because of the presence of a SO 3 − ion group in their structure, this polymer acts as an anionic polyelectrolyte, and from the perspectives of solid-state electrochemistry, this polymer can act as an excellent polymer host by providing many coordination sites for metal cations for transportation.…”

“…This slight variation causes the differences in conductivity and performance of the prepared gels. 271,351,354,361 In most cases, ions mainly transport from one electrode to another electrode by a ion hopping mechanism where charged ions hop by interacting with hydroxyl groups present on the polymer backbone. In addition to hydroxyl groups, other ionic and nonionic functional groups like sulfate in carrageenan, the amino group in chitosan, and etheric oxygen in agarose (see Figure 4) can also act as active sites for ion migration.…”

Continual escalation of our world population demands a vast and safe energy supply, the majority of which has been produced by fossil fuel sources. However, because of the huge energy demand, exponential depletion of these nonrenewable energy sources is inescapable and forthcoming in the coming century. Hence, utilization of renewable energy such as solar energy has gained attention because of its direct conversion of light energy into electrical power without any harmful environmental impacts. Solar energy has been harvested by different types of solar cells varying from inorganic to organic to the combination of both. Among them, the dye-sensitized solar cell (DSSC) with a biopolymer-based electrolyte has gained enormous consideration from researchers because of its sustainability, abundance of available raw material, low production cost, and easy production in addition to the low volatilization of electrolytes compared to liquid state electrolytes. This review aims to give an overview of the recent inputs in the development of biopolymer-based DSSCs. The performance of the biopolymers as electrolytes in DSSCs will be critically reviewed based on the physicochemical properties of the biopolymers. Key technical challenges and future research areas for the advancement of biopolymer-based DSSCs are also discussed.

“…For composites 1, 2, 3, 4 and 5, it was measured that it had the following mean pore diameter of 0.5, 0.42, 0.4, 0.45 and 0.75 microns respectively. Pore size of a membrane varied with the dependency on the optimum mixture of green based polymer with the material derivative of the composite [4]. The composite with the lowest mean pore diameter was favored for filtration.…”

Kappa-Carrageenan has been widely used as a gelling agent and stabilizer in the food industry. This research is an application of Kappa Carrageenan as polymer membrane with the combination of Hydroxyl Apatite obtained from the fishbone. Different weight percentages of K-Carrageenan and Fishbone were mixed to make a filtering media with the use of Glutaraldehyde as a crosslinking agent. Before the crosslinking, K carrageenan were pretreated with monochloroacetic acid, ethanol and sodium hydroxide to become an alkali-based solution that will be readily mixed with the hydroxyl apatite. Fishbone were converted to hydroxyl apatite through subjection in a high temperature dryer. Polymer membrane were characterized by evaluating its mechanical and physical properties such as elastic resistance, water permeability and mean pore size diameter with the use of force gauge, filtration due to gravity and scanned electron microscopy respectively. Based from the evaluation, composite with 60% KCarrageenan-40% Fishbone displayed the most feasible characteristic of a filtering media such as its mechanical strength and water permeability. Composite with 80% KCarrageenan-20% Fishbone has the smallest pore size in which a good characteristic also of a filtering media.
