Use of interleaved films to enhance the properties of all-cellulose composites

All cellulose composites (ACCs) were produced by partially dissolving alternating layers of cotton textile and film in solvent solution heating them under an applied pressure. The ionic liquid 1-ethyl-3-methylimidazolium acetate ([C2MIM][OAc]) combined with a co-solvent dimethyl sulfoxide (DMSO) was used this work, iterative approach employed to identify the combination [C2MIM][OAc] DMSO yield best balance composite mechanical properties. It revealed that addition interleaved yields higher Young’s modulus significantly interlayer peel strength compared processing without film. With optimised combination, improved from 2.2 ± 0.2 GPa 4.2 reached as high 917 2 N/m. In addition, there uniformity between longitudinal transverse properties, which we attribute overall increase adhesion.
