Transition layer slurry for membrane electrode and preparation method thereof, and membrane electrode and preparation method thereof

The invention provides transition layer slurry for a membrane electrode. The transition layer slurry comprises an ionomer, heteropolyacid, an anti-reverse oxide and a solvent, wherein the mass of theionomer is 5-20%, the mass of the heteropolyacid is 0-15% of the mass of the ionomer and does not include 0, the mass of the anti-reverse oxide accounts for 0-10% of the mass of the ionomer and does not include 0, the solvent is composed of deionized water, ethanol and ethylene glycol, the mass of the ethylene glycol accounts for 5-10% of the total mass of the solvent, the sum of the mass of the deionized water and the mass of the ethanol accounts for 90-95% of the total mass of the solvent, and the deionized water and the ethanol are mixed in any proportion. The invention further provides a preparation method of the transition layer slurry. Meanwhile, the invention further provides a membrane electrode prepared from the transition layer slurry and a preparation method of the membrane electrode. The transition layer slurry for the membrane electrode is simple and novel in composition and simple in preparation method, and the membrane electrode prepared from the transition layer slurrycan eliminate a gap between a catalyst layer and a proton exchange membrane, improve the proton conduction performance and reduce the anti-pole effect.

Solar cell gel electrolyte and preparation method and application thereof

The invention discloses a solar cell gel electrolyte and a preparation method and application thereof. In the invention, the gel electrolyte is prepared by adding novel dendritic ionic liquid into liquid electrolyte of non-polymeric ionic liquid, additive and iodine monomer, hermetically stirring the mixture for 1 to 20 hours at the temperature of between 50 and 140 DEG C and uniformly dissolvingthe novel dendritic ionic liquid. The gel electrolyte is dropwise added or injected into the space between a photoanode dye titanium dioxide membrane and a Pt electrode while the gel electrolyte is hot; the gel electrolyte is further heated and subjected to evacuation, so that the gel electrolyte is completely impregnated into the titanium dioxide membrane serving as a porous membrane; and the components are packaged to prepare a quasi-solid fully ionic liquid gel solar cell. The gel electrolyte prepared in the invention does not comprise conventional toxic solvents and thus has the advantages of ready availability, easy package and high stability and high efficiency of the cell. The cell has a few assembly processes and low cost. When a xenon lamp is utilized to simulate the sunshine at the room temperature environment, the measured maximum photoelectric conversion efficiency of the cell is 6.0 percent under the condition that the light intensity is 100mW / cm<2>.

Clindamycin metronidazole liniment and preparation process thereof

The invention relates to a clindamycin metronidazole liniment. The liniment specifically includes the following ingredients in percentage by weight: 16-24% of ethanol, 12-18% of glycerin, 15-30% of clindamycin hydrochloride or metronidazole, 3-5% of tazarotene, 3-7% of white vaseline, 0.02-0.1% of ethylparaben, and the balance of purified water. A preparation process of the liniment includes the following steps: firstly adding the ethanol and the glycerin into a stirring blending pot, uniformly sprinkling 2-4% of a transdermal absorbent, and then adding the metronidazole, the tazarotene and the ethylparaben; stirring the clindamycin hydrochloride in a stainless steel vessel until the clindamycin hydrochloride dissolves, and adding the dissolved clindamycin hydrochloride to the blending pot; and finally, adding the white vaseline and the purified water to reach the full amount, and performing stirring for 30 to 35 minutes to form the liniment. The liniment is novel in drug composition,has no irritation to the skin, and reduces the side effects such as dryness, desquamation and erythema. The production process of the invention is simple. The finished product is uniform and delicate,has high curative effect, and is easy to wash after external use.
