New protic ionic liquids (PILs) have been developed. The kinetic friction coefficients of ammonium salts of the alcolate, the carboxylate, and the sulfonate were from 0.23, 0.17, and 0.15, respectively, and 0.26 for Fomblin Z-DOL. PILs have better friction and wear properties compared to Z-DOL. The ammonium salts as a hydrophilic group have a lower(More)
This paper deals with the effect of the molecular structure of the newly synthesized protic ionic liquids (PILs) on the tribological and thermal properties. A higher &#x0394;pK<sub>a</sub> between the acid and base is effective for the thermal durability. It is more effective for the thermal stability to modify the sulfonate with a super base, and the DBU(More)
Bio-inspired surfaces that exhibit high contact angle and low contact angle hysteresis for various liquids and demonstrate mechanical durability and anti-smudge properties are of interest for various applications. The fabrication of such surfaces has often involved complex or expensive processes, required techniques that may not be suitable for various(More)
