Description

<p>Some examples of the development in polyurethane bioplastics are reported. It is important to design the composition, soft and hard segment, for building favorable micro phase separated morphology to achieve physical properties for specific applications. Castor oil-based polyol can be used for flexible polyurethane foams. The effect of dangling chain in polyurethane network is important factor in terms of resilience. Polycaprolactone-based thermoplastic polyurethane shows same level of BOD as cellulose in extracted seawater. A further study is necessary to elucidate the degradation mechanism of hard segment as well as soft segment.</p>
