Properties of fractionated and blended Polyhydroxyalkanoates
(2016) KTE720 20161Centre for Analysis and Synthesis
- Abstract
- The purpose of this project was to gain knowledge of polyhydroxyalkanoates’ (PHAs’) ability to be fractionated and form miscible blends for different structures, by using the methods: solvent/non solvent fractionation and co-dissolving in 2-butanol.The outcome of the fractions and blends was evaluated with differential scanning calorimetry (DSC), size exclusion chromatography (SEC), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The goal was to see if a specific structure of the original polymer was needed to obtain more narrow fractions or if a specific structure could facilitate the fractioning or miscibility.
- Popular Abstract
- In today’s society plastics are used everywhere and unfortunately a lot get disposed in nature. One way to make plastics more environmentally friendly materials is to instead use bioplastics. These plastics are not made out of oil, as conventional plastics are, but from other biological carbon sources and they can be produced by bacteria. A great thing with bioplastics is that they can decompose in nature and they will not leave any toxic residuals.
