dc.description.abstractPHAs have attracted attention as biodegradable alternatives to conventional thermoplastics and as biomaterials. By modifying their bioprocessesing we have manipulated their PHA material properties and produced a a natural–synthetic hybrid copolymer of polyhydroxyoctanoate-block-diethylene glycol (PHO--DEG). While the molecular weight ratio of these hybrids is approximately 900:1, the polymer displays amphipillic properties, A mixture of PHO and PHO–DEG were solvent cast from analytical grade chloroform and analysed using small-angle neutron scattering. A scattering pattern, easily distinguished above the background, was displayed by the films with a diffraction ring at q∼0.12 Å−1. This narrow ring of intensity is suggestive of a highly ordered system. with d-spacing of approximately 50 Å. Once can speculate that the hydrophilic synthetic blocks of the polymer chains may group together when the polymer is dissolved in organic solvent. This speculative model is supported by the formation of microporous films by these hybrids when processed by sold solvent evaporation under a humid flow (92% rH). © The Authorsen_AU
