Download the data
The dataset contains information on isothermal crystallisation of Poly(hydroxybutyrate-co-valerate) – PHBV – systems performed at different temperatures. The data was collected using Fourier Transform Infrared Spectroscopy (FTIR), using poly(hydroxybutyrate) – PHB – as well as PHBV systems of various hydroxyvalerate (HV) content – 7, 12, and 21 mol%. The temperature range span from ambient temperature to 150 °C.

Provenance & quality

The data was collected at the University of Strathclyde using an FTIR spectrometer with a heated stage. The sample was prepared by melting it between two Kapton sheets, using an aluminium oval mould. Then, the sample was placed in liquid nitrogen and placed at the FTIR stage, where it was equilibrated at a given temperature. The FTIR spectra were collected every 1 minute or 1.5 minutes and saved in .csv files. The data was then baseline-corrected and analysed for the changes in the peak distribution (i.e. maximum peak wavelength, peak intensity).
