On the Differences in Trimethylaluminum Infiltration into PMMA and PLA Polymers for Sequential Infiltration Synthesis: Insights from Experiments and First-Principles Simulations.

ABSTRACT: Sequential infiltration synthesis (SIS) is a powerful approach for templated growth of solid materials, such as oxides or metals, that exploits the difference in interaction of a precursor molecule with a polymer or block copolymer. While there have been studies showing that infiltration of trimethyl-aluminum (TMA) in polymers can be used to grow Al₂O₃, there are still many atomic level details of the SIS process that require more investigation, including the origin of the differences in infiltration of TMA into different polymers. In this paper, we investigated in detail the infiltration of Al₂O₃ into poly-(methyl methacrylate) (PMMA) and poly-(lactic acid) (PLA) experimentally and theoretically. SIS was performed in a standard ALD reactor, oper
