The intention was to determine the chemical interaction of silanized AgNPs with PMMA by Fourier transform infrared (FTIR) spectroscopy.
In-vitro comparative study.
This study is composed of four groups - 0.75% AgNP, 1.0% AgNP, 1.5% AgNP impregnated with PMMA, and nonimpregnated PMMA as control. The chemical nature of silanized AgNPs was studied using FTIR study.
The results showed the appearance of new peak between 1727/cm and 1436/cm, i.e., 1636.476/ cm, 1645.886/cm, and 1646.885/cm, representing the C = C stretch in the experimental groups, i.e., 2, 3, and 4, respectively. This peak confirms that coupling agent has chemically interacted with PMMA.
It can be concluded that the AgNPs coated with the silane coupling agent TMSPM has chemically reacted with PMMA.
通过傅里叶变换红外（FTIR）光谱法确定硅烷化 AgNPs 与 PMMA 的化学相互作用。
体外对比研究。
本研究由四组组成 - 0.75% AgNP、1.0% AgNP、1.5% 负载 PMMA 的 AgNP 和未负载 PMMA 的 PMMA 作为对照。使用 FTIR 研究研究了硅烷化 AgNPs 的化学性质。
结果表明在 1727/cm 和 1436/cm 之间出现了新的峰，即 1636.476/cm、1645.886/cm 和 1646.885/cm，分别代表实验组中的 C = C 伸缩，即 2、3 和 4。该峰证实偶联剂已与 PMMA 发生化学相互作用。
可以得出结论，用硅烷偶联剂 TMSPM 涂覆的 AgNPs 已与 PMMA 发生化学反应。
