聚甲基丙烯酸甲酯（PMMA）、聚醚醚酮（PEEK）和聚二甲基硅氧烷（PDMS）的超疏水性和超双疏水性聚合物表面通过两步工艺制备：(1)等离子体变形（即离子增强等离子体蚀刻同时粗化），等离子体化学取决于聚合物，随后(2)接枝自组装的全氟十二烷基三氯硅烷单层（SAMs）。根据是否存在蚀刻掩膜（即胶体微粒在其上自组装），可以获得随机或有序的分层微纳米纹理。我们证明了稳定的有机单层可以接枝到所有这些纹理聚合物表面上。单层沉积后，最初亲水的聚合物表面变成超疏水的，水和油的静态接触角b>为153度，十六烷b>为142度，并且有滞后性
Superhydrophobic and superamphiphobic toward superoleophobic polymeric surfaces of polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), and polydimethyl siloxane (PDMS) are fabricated in a two-step process: (1) plasma texturing (i.e., ion-enhanced plasma etching with simultaneous roughening), with varying plasma chemistry depending on the polymer, and subsequently (2) grafting of self-assembled perfluorododecyltrichlorosilane monolayers (SAMs). Depending on the absence or not of an etch mask (i.e., colloidal microparticle self-assembly on it), random or ordered hierarchical micro-nanotexturing can be obtained. We demonstrate that stable organic monolayers can be grafted onto all these textured polymeric surfaces. After the monolayer deposition, the initially hydrophilic polymeric surfaces become superamphiphobic with static contact angles for water and oils >153 degrees, for hexadecane >142 degrees, and hysteresis
