The structural and thermal properties of polyhydroxybutyrate (PHB) gels in dimethylformamide (DMF) are presented and discussed. The dilute and semi-dilute mixed PHB/DMF system undergoes a phase separation on cooling at a temperature Tgel, producing a gel in which the crystalline fraction is of the o...
