Poly(3-hydroxybutyrate) (PHB) is a polymer of polyhydroxyalkanoate family which when synthesized using biotechnological methods is biocompatible and biodegradable. However, this polymer’s complex crystallization behavior makes its properties difficult to predict. We performed Raman spectroscopy and surface free energy calculation on 5 samples of different molecular weights, which did not reveal any significant differences among the samples. We performed molecular dynamics simulations using 100 monomer long chains. Our simulation boxes of polymeric material were found to behave appropriately in response to changes in temperature, and the Young’s modulus of the or simulation boxes were found to be 2.0, 1.84 and 2.9 for production, annealing and quenching runs respectively.
