| Abstract Scope |
Vapor phase infiltration (VPI) is an innovative gas-phase technique for creating organic-inorganic hybrid materials. It involves diffusing vapor phase metalorganic precursors into organic polymers, transforming them into versatile hybrids used in lithography, film modification, and textile manufacturing. However, this method's reliance on highly pyrophoric and costly precursors like trimethylaluminum (TMA) poses significant challenges. To address this, we propose a novel approach for depositing metalorganics into polymer films using elements with accessible d-blocks, such as silicon. These elements form dative bonds with electron-donating polymers like poly(4-vinylpyridine) (P4VP), achieving effective precursor infiltration at room temperature and reducing toxic gas use. We verified the formation of polymer complexes using Solid-State Nuclear Magnetic Resonance (SSNMR) and X-ray Photoelectron Spectroscopy (XPS). Post-reaction spectral reflectance of P4VP films showed 30-35% growth with various silane precursors, consistent with thermogravimetric analysis (TGA), although higher molecular weight precursors exhibited slower growth rates. |
