Abstract

Aim: The intention was to determine the chemical interaction of silanized AgNPs with PMMA by Fourier transform infrared (FTIR) spectroscopy.

Settings and design: In-vitro comparative study.

Materials and methods: 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.

Results: 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.

Conclusion: It can be concluded that the AgNPs coated with the silane coupling agent TMSPM has chemically reacted with PMMA.

浸渍在聚（甲基丙烯酸甲酯）树脂中的硅烷化银纳米粒子的化学特性：体外研究。

目的：旨在通过傅立叶变换红外光谱（FTIR）确定硅烷化AgNPs与PMMA的化学相互作用：体外比较研究：本研究包括四组--0.75% AgNP、1.0% AgNP、1.5% AgNP 浸渍 PMMA 和作为对照的未浸渍 PMMA。利用傅立叶变换红外光谱研究了硅烷化 AgNPs 的化学性质：结果表明，在 1727/cm 和 1436/cm 之间出现了新的峰值，即 1636.476/cm、1645.886/cm 和 1646.885/cm，分别代表实验组（即 2、3 和 4）中的 C = C 伸展。该峰值证实偶联剂与 PMMA 发生了化学作用：可以得出结论：涂有硅烷偶联剂 TMSPM 的 AgNPs 与 PMMA 发生了化学反应。
