    摘要: Bioplastic compositions containing between 2 wt. % and 25 wt. % of at least one starch, between 40 wt. % and 65 wt. % of at least one plasticizer, and between 1 wt. % to 10 wt. % of at least one acid are used as insulation materials. A method of making a bioplastic composition includes the steps of heating a first aqueous mixture containing at least one plasticizer and at least one acid; adding at least one starch to the first aqueous mixture to produce a second aqueous mixture; heating and mixing the second aqueous mixture to produce a precipitate; and separating the precipitate from residual liquid of the second aqueous mixture to produce a bioplastic composition.

    摘要: Fabricating a layer including lithium lanthanum zirconate (Li7La3Zr2O12) layer includes forming a slurry including lanthanum zirconate (La2Zr2O7) nanocrystals, a lithium precursor, and a lanthanum precursor in stoichiometric amounts to yield a dispersion including lithium, lanthanum, and zirconium. In some cases, the dispersion includes lithium, lanthanum, and zirconium in a molar ratio of 7:3:2. In certain cases, the slurry includes excess lithium. The slurry is dispensed onto a substrate and dried. The dried slurry is calcined to yield the layer including lithium lanthanum zirconate.

    摘要: A method for preparing a super absorbent polymer and a superabsorbent polymer prepared from the same are disclosed herein. In some embodiments, a method includes mixing super absorbent polymer particles, water and an additive form a hydrated super absorbent polymer, wherein the super absorbent polymer particles comprise a base polymer powder including a cross-linked polymer polymerized from a water-soluble ethylenically unsaturated monomer having an acidic group of which at least a part is neutralized, and a surface cross-linked layer formed on the base polymer powder, wherein the surface cross-linked layer is formed by further cross-linking the cross-linked polymer, and wherein the additive including a polyoxyalkylene aliphatic hydrocarbon ether carboxylic acid. The method can appropriately control the water content of the super absorbent polymer by water-addition or the like to suppress crushing or the like during transfer, and also can suppress deterioration of physical properties.
