Abstract: A proton conduction material having high proton conductivity and exhibiting high reactive gas permeability regardless of the percentage of water content is provided. This proton conduction material consists of a polymer material whose molecular structure has a strong acid functional group. This polymer material consists of a polymer of a mixture of a monomer having an end structure expressed by a formula (1) or a vinyl radical and a monomer expressed by a formula (2). A strong acid functional group is included in the structure of both the monomers. It is to be noted herein that R1, R2, R3, R4, R5 and R6 represent a hydrocarbon radical, a fluoro-substituted hydrocarbon radical, or a trimethylsiloxy radical. Because introduction of a structure in which a hydrocarbon radical is bonded to silicon weakens interaction and causes bulkiness, gaps are created among atoms. If the number of the gaps among the atoms increases, the diffusion coefficient of reactive gases increases.

Abstract: Disclosed is a powder coating composition containing a powder coating resin and a polyhedral oligomeric silsesquioxane (“POSS”) compound.

Abstract: The nanoscopic dimensions of polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) materials ranges from 0.7 nm to 5.0 nm and enables the thermomechanical and physical properties of polymeric materials to be improved by providing nanoscopic reinforcement of polymer chains at a length scale that is not possible by physically smaller aromatic chemical systems or larger fillers and fibers. A simple and cost effective method for incorporating POSS/POS nanoreinforcements onto polymers via the reactive grafting of suitably functionalized POSS/POS entities with polymeric systems amenable to such processes is described. The method teaches that the resulting POSS-grafted-polymers are particularly well suited for alloying agents by nongrafted POSS entitles such as molecular silicas. The successful alloying of POSS-polymers is aided because their interfacial tensions are reduced relative to non-POSS containing systems.
