Glassy dynamics of two poly(ethylene glycol) derivatives in the bulk and in nanometric confinement as reflected in its inter- and intra-molecular interactions
Jasiurkowska-Delaporte, Małgorzata; Kossack, Wilhelm; Kiprop Kipnusu, Wycliffe; Sangoro, Joshua; Iacob, Ciprian; Kremer, Friedrich AIP Publishing (2018-08)The inter- and intra-molecular interactions as they evolve in the course of glassy solidification are studied by broadband dielectric—and Fourier-transform infrared—spectroscopy for oligomeric derivatives of poly(ethylene ... -
Glassy dynamics predicted by mutual role of free and activation volumes
Kiprop Kipnusu, Wycliffe; Elsayed, Mohamed; Iacob, Ciprian; Pawlus, Sebastian; Krause-Rehberg, Reinhard; Paluch, Marian Royal Society of Chemistry (2019)Broadband Dielectric Spectroscopy (BDS) at elevated pressures and Positron Annihilation LifetimeSpectroscopy (PALS) are employed to elucidate the importance of the ratio of activation and freevolumes during vitrification. ...
