Abstract
Poly(beta -hgdroxybutyrate) (PHB) is st bacteria storage biodegradable poly ester that is considered to be a natural substitute for synthetic thermopla stics in many applications. However, brittleness hampers its utility. This study shows that oriented elastic fibers of PHB with favorable mechanical p roperties (360-MPa tensile strength and 5.6-GPa Young's modulus) can be pro duced by the spinning and drawing of a concentrated PHB gel using a three-s tage fiber processing technique.
