基于原子层沉积化学的顺序气相渗透（SVI）方法允许通过金属-有机气相试剂扩散到聚合物基底中来产生聚合物-无机杂化材料。本研究调查的酯，酰胺，和羧酸官能团的聚（甲基丙烯酸甲酯）（PMMA），聚（乙烯吡咯烷酮）（PVP），和聚（丙烯酸）（PAA），分别在三甲基铝（TMA）蒸汽的存在下的反应性。本工作通过原位傅里叶变换红外光谱和从头算量子化学分析探讨了这些官能团可能的反应机理。的温度下
The sequential vapor infiltration (SVI) method, based on atomic layer deposition chemistry, allows the creation of a polymer-inorganic hybrid material through the diffusion of metal-organic vapor reagents into a polymer substrate. This study investigates the reactivity of the ester, amide, and carboxylic acid functional groups of poly(methyl methacrylate) (PMMA), poly(vinylpyrrolidone) (PVP), and poly(acrylic acid) (PAA), respectively, in the presence of trimethylaluminum (TMA) vapor. This work explores the possible reaction mechanisms of these functional groups through in situ Fourier transform infrared spectroscopy and ab initio quantum chemical analysis. At temperatures of
