采用单次引发化学气相沉积(I-CVD)工艺制备了一种坚固耐用的超两亲海绵(SA-海绵)。聚甲基丙烯酸甲酯(Poly(3，3，4，4，5，5，6，6，7，7，8，8，9，9，10，10，10-heptadecafluorodecyl)(PFDMA)是在I-CVD过程中通过氟烷基丙烯酸酯聚合而沉积在商业海绵上的。这种PFDMA通过I-CVD过程的一个步骤在近乎室温下共形地涂覆在海绵结构的外部和内部。由于海绵固有的多孔结构和氟基PFDMA的疏水性质，所制备的SA-海绵不仅具有超疏水性能，而且还具有超疏油性能。此外，所制备的SA-海绵在物理和化学损伤方面是坚固的。制备的SA-海绵可用于多用途应用，如透气性液体分离器。
A robust superamphiphobic sponge (SA-sponge) is proposed by using a single initiated chemical vapor deposition (i-CVD) process. Poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl methacrylate) (PFDMA) is deposited on a commercial sponge by the polymerization of fluoroalkyl acrylates during the i-CVD process. This PFDMA is conformally coated onto both the exterior and interior of the sponge structure by a single step of the i-CVD process at nearly room temperature. Due to the inherent porous structure of the sponge and the hydrophobic property of the fluorine-based PFDMA, the demonstrated SA-sponge shows not only superhydrophobicity but also superoleophobicity. Furthermore, the fabricated SA-sponge is robust with regard to physical and chemical damage. The fabricated SA-sponge can be utilized for multi-purpose applications such as gas-permeable liquid separators.
