An ion-exchange membrane may be continuously coated by depositing a catalyst composition on a release surface, drying the catalyst at an elevated temperature and then transferring the dried catalyst layer onto an ion-exchange membrane by applying pressure at a different elevated temperature. A quinoxaline derivative represented by the general formula is provided. The size of the discrete, spaced-apart ferroelectric polymer structures may be tied to a specific photolithography minimum feature dimension. A protective structure is provided on the insulating material such that it covers the entire circumference thereof. The dispersion solution for drilling is used for the well drilling method such as hydraulic fracturing method, rotary drilling method or riserless drilling method. A process for making such a composition is also disclosed which involves subjecting a particulate material to plasma after which a water-soluble organic monomer is graft polymerized onto at least a portion of the particulate material.
