Abstract

Fluoro-Decyl POSS (FDP) has shown strong potential as a water repellant surface coating. Additionally, Fomblin is a solvent believed to have the ability to control the crystallization of POSS compounds on surfaces. Controlling the crystallization is key to improving water repelling abilities of surfaces. Thus, dip coating FDP and Fomblin onto surfaces is being investigated for water repulsion, mechanical stability, and deposition feasibility. However, in order for this to be successful, POSS must be soluble in Fomblin. Temperature dependence of solubility of Fluoro-Hexyl, Fluoro-Octyl, Fluoro-Decyl POSS in Fomblin was tested using Dynamic Light Scattering. The values were compared, and it was shown that Fluoro-Hexyl Poss had a weak solubility-temperature. Both Fluoro-Octyl and Fluoro-Decyl POSS had strong temperature dependences. However, Fluoro-Decyl Poss appeared to stay super saturated after the solution cooled, and failed to recrystallize.
