The study of hydrophilic characteristics of ethylene glycol

This paper describes the way to measure ethylene glycol resistance (Ω). The electronic sensing of hydrophilic characteristics was design to measure ethylene glycol moisture contain in real-time. Many liquids contain the glycol such as brake fluid, antifreeze and cosmetics. The percent of water contain may affect those liquids functions. It will measure the ethylene glycol resistance (Ω) and could be converted into voltage for the use of moisture meter. The relation between ethylene glycol with moisture contain and its resistance (Ω) is close to linear. The hydrophilic characteristics is the molecular model of OH structure which has a hydrogen atom (H) bonded to the oxygen atom (O); it will absorb the electron cloud at the outer layer of hydrogen atom; so the electrons within O–H bond have a higher probability of appearance around the oxygen atom. The O–H bond is similar to a chemical bond which can absorb the water molecules.
