“…The morphology of neat carrageenan and the different [Bmim][FeCl 4 ]/carrageenan blends was analyzed by SEM, as shown in the representative cross-sectional images in Figure . Neat carrageenan presents a layered and nonporous structure, ascribed to its semicrystalline structure . Upon IL incorporation (10 and 20 wt %) into the polymer matrix, the nonporous structure is preserved but becomes more compact due to the good distribution of the IL within the matrix (Figure b,c).…”

For reducing the environmental impact of electronic systems (e-waste), increasingly implemented in the scope of the digitalization of society, this work reports on the development of a sustainable pressure sensor based on the combination of natural polymer carrageenan and ionic liquid (IL) 1-butyl-3-methylimidazolium tetrachloroferrate ([Bmim][FeCl 4 ]). Different IL contents were incorporated into the carrageenan matrix (10, 20, and 40 wt %) to evaluate the influence of IL content on the final properties of the hybrid materials. No variations are induced in the chemical structure of carrageenan by the inclusion of the IL. On the other hand, the thermal stability of the polymer decreases with increasing IL content, as well as the Young modulus that decreases from 748 MPa for pristine carrageenan to 437 MPa for the composite with 40 wt % IL content. The ionic conductivity increases up to 8.74 × 10 −9 S/cm for the sample comprising 40 wt % IL. The recyclability of the developed materials has been accessed, and the potential of the blends for the development of printable pressure sensors has been demonstrated.

“…The XRD pattern of pure I-carrageenan and I-carrageenan with Copper Sulphate Pentahydrate (ICS) is given in Figure 2. 14 As mentioned in the literature survey, the pure I-carrageenan polymer exhibits an amorphous nature and there exist small humps at 2θ = 20°and 30°. 15 While increasing the concentration of the salt in the order of 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.% (5 ICS, 10 ICS, 15 ICS and 20 ICS), the intensity of the hump at 2θ = 30°is decreased.…”

Biodegradable polymer films composed of Iota-Carrageenan and Copper Sulphate Pentahydrate (CuSO4.5H2O) were prepared by using the Solution Casting process. To investigate the optical property, different wt.% of CuSO4.5H2O were added to I-carrageenan polymer films. X-Ray diffraction analysis was used to study the structural properties of prepared electrolytes. FTIR study revealed the complexation between the polymer and the salt. The increase in the amorphous nature of the film by the addition of the salt was confirmed using an X-Ray Diffraction (XRD) pattern. The functional group and interaction between the different components present in the polymer film are observed from Fourier Transform Infrared (FTIR) analysis, implying that the addition of (CuSO4.5H2O) salt causes microstructural differences in the polymer film. The UV-Visible Spectrometer was used to record the optical properties like the absorption coefficient, extinction coefficient, and optical bandgap energy of the polymer blend electrolytes. From this, it was observed that the absorption value was increased with the addition of salt. The optical band gap was also recorded and it was observed that 20 wt.% of CuSO4.5H2O added film was found to have a higher energy gap (4.3 eV) compared with the other.
