“…Such materials offer exclusive advantages of environment affability, cost effectiveness, ease of availability, biodegradability, and sustainability 1, 2. Several bio‐based precursors have been modified by conventional reactions, e.g., epoxidation, hydroxylation, acrylation, vinylation, urethanation, and others 3–9. Recently, chitosan, starch, cellulose, polycaprolactone, and vegetable seed oil (VSOs) based polymeric resins have been modified by sol–gel and reinforcement techniques to improve their performance as well as broaden their areas of applications 10–17.…”
