相较于表面易损伤、压力稳定性差的超疏水表面,具备特殊浸润性的光滑液体灌注表面(SLIPS)在油水分离膜材料的开发上有良好的应用前景。本文使用聚丙烯(PP)和聚酯(PET)纤维膜作为基底,通过一步浸涂法在基底上构造了ODA/PDMS疏水粗糙结构,在其上灌注润滑油,制备了一种具备SLIPS的仿生光滑液体灌注膜(SLIM-ODA/PDMS)。这种光滑液体灌注膜具有良好的疏液性和较好的重力下油包水乳液分离能力,分离率在99.8%以上,这为新型油水分离材料的开发提供了思路。 相似文献

An approach based on interferometry technique is proposed for three-dimensional( 3D) bistatic inverse synthetic aperture radar( ISAR) imaging. It is converted to a monostatic problem by using the theory that a bistatic radar equals a monostatic radar located on the bisector of bistatic angle. Then,interferometric phases extracted from a pair of cross shaped antennas are used to estimate the height and associated rotational velocity.Finally,numerical simulations are provided to evaluate this method. 相似文献
