High-entropy ceramic nano-material for PEI membrane as well as preparation method and application of high-entropy ceramic nano-material
The invention relates to the technical field of high-entropy ceramic materials, and discloses a high-entropy ceramic nano-material for a PEI membrane and a preparation method and application thereof. The preparation method comprises the following steps: dissolving a metal source into water to prepare a metal source solution; the metal source comprises water-soluble salts of magnesium, copper, zinc, cobalt and nickel, or comprises water-soluble salts of tantalum, niobium, titanium, zirconium and hafnium; dissolving a precipitant into water to prepare a precipitant solution; dropwise adding the precipitant solution into the metal source solution, and fully precipitating to obtain a floccule suspension; carrying out hydrothermal reaction on the floccule suspension, and separating a product to obtain a precursor; and carrying out heat treatment on the precursor to obtain the high-entropy ceramic nano material. The high-entropy ceramic nano-material prepared by the invention has better dielectric property, and can generate stronger interface polarization with a PEI substrate, so that the dielectric property of a PEI film can be effectively improved, and the PEI film has higher dielectric constant and lower dielectric loss.
本发明涉及高熵陶瓷材料技术领域，公开了一种PEI膜用高熵陶瓷纳米材料及其制备方法和应用。该制备方法包括以下步骤：将金属源溶解到水中，制成金属源溶液；所述金属源包括镁、铜、锌、钴和镍的水溶性盐，或者包括钽、铌、钛、锆和铪的水溶性盐；将沉淀剂溶解到水中，制成沉淀剂溶液；将沉淀剂溶液滴入金属源溶液中，充分沉淀后，获得絮状物悬浮液；将絮状物悬浮液进行水热反应，分离产物，获得前驱体；对前驱体进行热处理，获得高熵陶瓷纳米材料。本发明制得的高熵陶瓷纳米材料自身具有较好的介电性能，且能够与PEI基体之间产生较强的界面极化，因而能有效提高PEI膜的介电性能，使其具有较高的介电常数和较低的介电损耗。
