概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
Biodegradable alternatives to plastic are in need for a sustainable future. Here we focus on natural resources that are available in Hokkaido, chitin, chitosan, citric acid, etc. Materials were processed into pastes either with or without adding a crosslinking agent. The specimen were formed under various conditions and their morphology and stregths was investigated.
実験 / Experimental
We were forming specimen for tensile strength measurements by making pastes containing chitin, chitosan, and/or crosslinking agent. The pastes were added to a standard testing form and samples were prepared at various temperatures (between 80 and 220°C) and pressures of up to 40 MPa, and investigated by SEM and IR spectroscopy.
結果と考察 / Results and Discussion
The strength became already higher at moderate temperatures of 80°C and crosslinked materials that
did not swell in water could be prepared that had a tensile strength
comparable to polypropylene. Furthermore, biodegradability experiments were carried out in lakes, rivers, soil and sea water. We found that the crosslinked samples showed enhanced stability against biodegradation.
