Investigation of the shear-mechanical and dielectric relaxation processes in two monoalcohols close to the glass transition
Shear-mechanical and dielectric measurements on the two monohydroxy (monoalcohol)
molecular glass formers 2-ethyl-1-hexanol and 2-butanol close to the glass-transition
temperature are presented. The shear-mechanical data are obtained using the piezoelectric
shear-modulus gauge method covering frequencies from 1 mHz to 10 kHz. The shear-
mechanical relaxation spectra show two processes, which follow the typical scenario of a
structural (alpha) relaxation and an additional (Johari–Goldstein) beta relaxation. The …
