Macromolecular Rapid Communications

Johnson, Ross S.; Washburn, Cody M.; Staton, Alan W.; Moorman, Matthew W.; Manginell, Ronald P.; Dugger, Michael T.; Dirk, Shawn M.

The synthesis of two new polyphenylene vinylene (PPV) precursor polymers which can be thermally induced to eliminate pentanol is presented. Pentanol has recently been discovered to be a very useful lubricant in MicroElectroMechanical Systems. The utilization of the elimination reaction of precursor polymers to PPV as a small molecule delivery platform has, to the best of our knowledge, not been previously reported. The elimination reactions were examined using thermal gravimetric analysis, gas chromatography, and UV-Vis spectroscopy. Using PPV precursors allows for (1) a high loading of lubricant (one molecule per monomeric unit), (2) a platform that requires relatively high temperatures (>145 °C) to eliminate the lubricant, and (3) a non-volatile, mechanically and chemically stable by-product of the elimination reaction (PPV). The "on-demand" delivery of a vapor-phase lubricant to MicroElectoMechanical Systems (MEMS) will allow for scheduled or as-needed lubrication of the moving components, improving the performance, reliability, and lifespan of the devices. A delivery system utilizing a newly designed microhotplate along with two new precursor poly(p-phenylene vinylene) polymers that thermally eliminate a pentanol lubricant is described.
