Modification of Thermal and Mechanical Properties of Polyhydroxybutyrate (PHB) through Addition of Bio-based Plasticizing Materials and Additive Manufacturing Processing
DownloadFall 2018
The non-degradable polymers currently used for commercial production and application may be inexpensive; however, their excessive use is leading to unprecedented amounts of plastic waste and extensive environmental damage. The demand for biologically-derived, biodegradable polymers is therefore...
