Mathematical Model of Water Absorption in Arrowroot Starch-Chitosan Based Bioplastic

Water Absorption of Chitosan, Collagen and Chitosan/Collagen Blend Membranes Exposed to Gamma-ray Irradiation

TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...

Water absorption and degradation characteristics of chitosan-based polyesters and hydroxyapatite composites.

Blends of chitosan and biodegradable synthetic aliphatic polyesters (polycaprolactone, poly(butylene succinate), poly[(butylene succinate)-co-adipate], poly[(butylene terephthalate)-co-adipate], and poly(lactic acid)) were injection-molded. These samples were immersed in isotonic solution at 37 degrees C for a period of 60 d. The water uptake and the degradation properties, as measured by the l...

Physicochemical Parameters Study of Chitosan-starch- Glutaric Acid in Acetic Acid-water Mixtures

Knowledge of the physicochemical parameters values produced by the utilization of the polymer blends is important because of the effect that it has on the operational cost of several stages of the industrial process Chitosan/starch solutions of different variable concentrations from (90/10 to10/90) are prepared in dilute acetic acid solution (1%). Glutaric acid solution concentration is 1% fixe...
