| Abstract: The purpose of this study was to analyse the influence of a deuteron beam irradiation on the viscosity and molecular weight of chitin. Chitin powder was irradiated with a 2 GeV deuteron beam than it was solubilized in a LiCl/DMAc solution. Viscosity measurements put forward a reduction in viscosity and viscosity-average molecular weight from 690 kDa to 570 kDa. These measurements were coupled with an FTIR spectroscopic analysis to see qualitative modifications in chemical composition. |
