| Abstract (en) | We have investigated the fragility of glycerol, propylene carbonate, and meta-fluoroaniline at pressures up to 700 MPa using dielectric spectroscopy. All three small-molecule glass formers do not show a pressure dependence of fragility within experimental error. The ratio of glass transition temperature and Vogel-Fulcher-Tammann temperature is pressure independent. The results are discussed in the frame of the defect diffusion model. |
