从聚(苯乙烯)-b-聚(甲基丙烯酸甲酯)二嵌段共聚物薄膜(PS-b-PMMA,体积比70:30)在硅上的纳米多孔模板的制造需要精确控制界面能,以实现PMMA圆柱形微区相对于衬底的垂直取向。为了提供一种简单,快速,但可调的表面中和方法,我们研究了PS-b-PMMA二嵌段共聚物薄膜在用十八烷基二甲基氯硅烷(ODMS)部分单层改性的硅基底上的自组装有序性,即,接枝密度小于最大可能单层表面覆盖率的ODMS层。我们在此展示了在这些部分ODMS自组装膜上从退火的PS-b-PMMA二嵌段共聚物薄膜制备纳米多孔PS模板。
The fabrication of nanoporous templates from poly(styrene)-b-poly(methyl methacrylate) diblock copolymer thin films (PS-b-PMMA, volume ratio 70:30) on silicon requires precise control of interfacial energies to achieve a perpendicular orientation of the PMMA cylindrical microdomains relative to the substrate. To provide a simple, rapid, yet tunable approach for surface neutralization, we investigated the self-assembled ordering of PS-b-PMMA diblock copolymer thin films on silicon substrates modified with a partial monolayer of octadecyldimethyl chlorosilane (ODMS), i.e., a layer of ODMS with a grafting density less than the maximum possible monolayer surface coverage. We demonstrate herein the fabrication of nanoporous PS templates from annealed PS-b-PMMA diblock copolymer thin films on these partial ODMS SAMs.
