Annotation
Dialdehyde inulin was synthesized by periodate oxidation of inulin with controlled degrees of oxidation ranging from 5% to 35%. The oxidation introduced reactive aldehyde groups through cleavage of vicinal diols, enhancing the reactivity of the polysaccharide. The obtained dialdehyde inulin samples were reacted with sericin at different mass ratios (1:1, 1:2, and 2:1) to form composite materials. The interaction occurred via Schiff base formation between aldehyde and amino groups, resulting in a covalently crosslinked structure. FTIR analysis confirmed the formation of imine -C=N-) linkages and the reduction of aldehyde groups. The properties of the resulting composites were found to depend on the degree of oxidation and component ratio. The results demonstrate an effective approach for the preparation of sericin-dialdehyde inulin composites with potential applications as biodegradable materials.
