Iota-carrageenan is a polysaccharide that reveals antiviral activity by binding to viruses, inhibiting its replications and, consequently, its viral propagation. The main purpose of the treatment is the relief of symptoms however, the medication is often associated with adverse effects. Although benign, its symptoms result in economic burden and can lead to severe or even fatal complications in children, elderly and groups with comorbidities.

Meanwhile, the scanning electron microscope observation reveals that the carboxymethyl ɩ-carrageenan film becomes smoother than ɩ-carrageenan film which supports the ionic conductivity enhancement. X-ray diffraction analysis shows that the chemical modification of ɩ-carrageenan increases the amorphous phase of polymer electrolyte film. Thermal gravimetric analysis result shows that the modified powder and film were stable up to 300 ☌. The polymer electrolytes films were prepared by solution casting technique. The produced powders were characterized by 1H nuclear magnetic resonance and attenuated total reflection Fourier transform infrared spectroscopy to confirm the substitution of targeted functional in ɩ-carrageenan. ɩ-Carrageenan was reacted with monochloroacetic acid to produce carboxymethyl ɩ-carrageenan. A new type of solid polymer electrolyte based on iota (ɩ)-carrageenan derivative has been investigated.
