Merging of the α and β relaxations in polybutadiene: A neutron spin echo and dielectric study

Arantxa Arbe、Dieter Richter、Juan Colmenero 等 4 位作者1996-10-01Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

The local dynamics of 1,4 polybutadiene below and above the merging of the \ensuremath{\alpha} and \ensuremath{\beta} relaxations have been investigated by combining neutron spin echo (NSE) and dielectric spectroscopy. The study of the dynamic structure factor measured by NSE over a wide momentum transfer range allows…

Electrochemical Formation of Polyaniline in Selenic Acid

Heqing Tang、Akira Kitani、Masaru Shiotani1996-10-01Journal of The Electrochemical Society

The electrochemical formation of polyaniline (PAn) was investigated in selenic acid. The cyclic voltammetry of selenate in the potential window from −0.15 to 0.8 V, indicates that the electropolymerization of aniline is not affected by the oxidizing ability of selenic acid. The growth rate of PAn observed at a potenti…
