Abstract

In recent years, there has been much effort to provide eco-friendly and biodegradable materials for the next-generation composite products owing to global environmental concerns and increased awareness of renewable green resources. In this context, the present study reports the preparation of green composite materials from natural, biocompatible, and biodegradable chitosan films reinforced with seashells and waste glass using a solution-casting method. The surface morphological features and chemical interactions of the composite films were studied using SEM, EDS, FTIR, and XRD techniques. The swelling degree (SD) and hardness properties of composites with various reinforcement weight proportions are compared to those of pure chitosan film. The reinforced materials, especially CSG532 and CSG523 with porous rod-like surface textures, improved the hardness of chitosan by two-fold. The SDs of the hybrid composites were also significantly lower than those of the unmodified chitosan film.
