In this work we explore the use of room temperature ionic liquid doped ionomers as the sensing material for volatile organic compounds (VOCs). Pixels of a monolithic, micromachined quartz crystal resonator (μQCR) array were functionalized using a sulfonated, aromatic, high thermal stability polymer as a template which is able to contain high amount of ionic liquids (up to 200 wt %). Ionic liquid:...
A series of poly(arylene ether triazine) homopolymers were synthesized that contain pendant diphenylamine groups. The polymers had inherent viscosities from 0.66 to 1.01dL/g in DMAc at 25°C, thermal stabilities >500°C in air, glass transition temperatures from 156°C to 309°C, and solubilities that depended upon the bis(4-fluorophenyl) monomer that was used for polymerization. Polymers could be...
A series of polymers was synthesized that contain a rigid aromatic backbone connected through triazine linkages that are cross-linked by flexible diamine-terminated poly(ethylene oxide) oligomers. Polymers were made that contained both hydrophilic sulfonated aromatic and hydrophobic pyridinium triflate backbones. Thermal and mechanical properties of the resulting polymer films were studied, as well...
