Super Molecular-polarization Phenomenon of Poly (ethylene glycol) in Deionized Water

A new discovery describing nonionic surfactant poly(ethylene glycol) being added into deionized water, electrical conductivity of the water would show a remarkable increase phenomenon. The mechanism study indicated that the electrical conductivity increase of the water doped some PEG was formed by super-polarization of a PEG molecule on the water molecule. A PEG molecule can form a super polarization body in the water, which will generate a strong polarization effect on the water molecule, thereby increasing water ionization degree and makes the electrical conductivity of water greater.

Super Molecular Polarization of Polyoxyethylene-Water Binary Systems

When polyoxyethylene-based non-ionic surfactants were added to deionized water, the electrical conductivity of the water increased. The increase was proportional to the surfactant concentration until a maximum value was reached at concentrations between 20∼25%. As long as the macromolecules contained a polyoxyethylene structure (-C-C-O-) there was noticeable molecular polarization in aqueous solution. The highest polarization capacity was observed at surfactant concentrations of 20∼25%.

Influences of ionic environment on self-assembly behaviour of hyperbranched polymers

Detection of electrical conductivity is carried out to study the characteristics of adsorptive action between several ions such as Ca2+, Cl−, Na+, and hyperbranched comb-like polymers. The results show that the strength of their adsorptions is in the descending order as follows: Ca2+ >   > Cl− (Na+). CaCl2 solution will significantly reduce the electrical conductivity of hyperbranched comb-like polymers, whereas NaCl solution will increase it obviously. Due to association and dispersion of ions in hyperbranched comb-like polymers; all salt ionic solutions can enlarge the critical micelle concentration of hyperbranched comb-like polymers.
