Elucidating the Kinetics and Thermodynamics of Organic Vapor Phase Infiltration and Molecular Layer Deposition for Dissolution Resilient Polymers.

ABSTRACT: Vapor phase chemical synthesis techniques, such as atomic layer deposition (ALD) and vapor phase infiltration (VPI), enable molecular-level tailoring of polymeric materials through deposition or incorporation of inorganic components. However, benefits are often paired with compromised mechanical stability and organic-inorganic bonds that are prone to degradation via hydrolysis. To address these limitations, we investigate all-organic VPI and molecular layer deposition (MLD) chemistries as a strategy for enhancing polymer properties. We examine the reaction-diffusion kinetics and thermodynamic behavior of three aromatic step-growth polymerization reactions: polyamide (isophthaloyl chloride + m-phenylenediamine, MPD), polyurea (1,4-phenylene diisocyanate + MPD), and polyimine (terephthalalde
