Outline of Final Research Achievements

We established a broadband dielectric spectrum measuring system covering a frequency range from 1 M to 3 GHz. The obtained dielectric spectra of aqueous solution of hydrophilic polymers revealed that the relaxation mode assigned to dangling water hydroxy groups without forming hydrogen bonding to other water molecules decreased with increasing concentration. On the other hand, a relaxation mode was newly found, and its intensity increased with increasing the concentration. These proposed that the (hydrophilic) hydration is resulted from hydrogen bond formation between a dangling water hydroxy group and a hydrophilic one.
Dielectric spectra demonstrated that water hydroxyl groups adjacent nitro and cyano groups do not form hydrogen bonds to the groups, but cause only dipole-dipole interactions, then they become dangling ones. Since nitro and cyano groups possess intermediate characteristics between hydrophilic and hydrophobic groups, they are classified into hydroneutral groups.
