Ultrasound-assisted depolymerization of kappa-carrageenan and characterization of degradation product

Ultrasonics Sonochemistry, 2021
Degradation of polysaccharides to afford low-molecular-weight oligosaccharides have been shown to produce new bioactivities that are not present in the starting material. The simplicity of ultrasonic treatment in the degradation of a polysaccharide, such

Synthesis and characterization of modified κ-carrageenan for enhanced proton conductivity as polymer electrolyte membrane. [PDF]

PLoS ONE, 2017
Polymer electrolyte membranes based on the natural polymer κ-carrageenan were modified and characterized for application in electrochemical devices. In general, pure κ-carrageenan membranes show a low ionic conductivity.
