The valence orbital (2s and 2p) energy levels of the fluorine atom are stabilized remarkably well by a large positive charge of the nucleus and the absence of shielding eifects by inner-shell electrons. The orbital energy level of the 2p lies at —18.6 eV. This is 5 eV lower than that of the proton s ls-orbital [6]. 

The ethylene glycol derivatives exhibit their thermotropic mesophases only mono-tropically, see Table 4 interestingly, their mesomorphic phase range can be stabilized remarkably by addition of water. In the latter case, the clearing temperature increases whereas the transition temperature of the SmB-SmA transition decreases. The authors conclude, here, that the formation of hydrogen bonds between adjacent molecules is responsible for their mesophase formation [7 8].

It must be noted that widespread electrochemical processes and deviees use poly (perfluorosulfonic acid) ionic polymers. These materials exhibit [1-20] good chemi-eal stability, remarkable mechanical strength, good thermal stability and high elec-trieal eonduetivity when sufficiently hydrated and made into a nanoeomposite with a eonduetive phase such as metals, conductive polymers or graphite. As described elsewhere [7], a number of physical models have been developed to understand the meehanisms of water and ion transport in ionic polymers and membranes. Morphologieal features influence transport of ions in ionie polymers. These features...
