Beschreibung
Zusammenfassung:	The invention discloses a non-woven fabric membrane material for an electronic element and a preparation method of the non-woven fabric membrane material. The non-woven fabric membrane material for the electronic element comprises a polyetherimide base material and aerogel. The aerogel is disposed on the polyetherimide substrate, and has a water content of 0.7% to 0.9% and a porosity of 85% to 95%. The non-woven fabric membrane material disclosed by the invention has a low dielectric constant value, a low dielectric loss factor and low hygroscopicity, so that the non-woven fabric membrane material is suitable for electronic elements. 一种用于电子元件的无纺布膜材及其制备方法，用于电子元件的无纺布膜材包括聚醚酰亚胺基材以及气凝胶。气凝胶配置于聚醚酰亚胺基材上，且具有介于0.7％至0.9％间的含水率以及介于85％至95％间的孔隙率。本揭露的无纺布膜材具有低的介电常数值、低的介质损耗因素以及低的吸湿性，从而适用于电子元件中。
