Abstract

Gold nanoparticles (AuNPs) display surface plasmon resonance (SPR) as a result of their irradiation at a targeted light frequency. SPR also results in heat production that increases the temperature of the surrounding environment, affecting polymerization. The aim was to investigate the SPR effect of AuNPs on a dimethacrylate-based photopolymer system. The tested composites were designed to overlap the illumination required for the polymerization and the plasmon effect. The 5 nm-sized dodecanethiol capped AuNPs were applied in different concentrations in the matrix that were irradiated with green light (λ = 532 nm), where the Irgacure 784 photoinitiator also absorbs the light. The plasmonic effect was investigated for the refractive index change by surface plasmon resonance imaging (SPRi) supplemented by ellipsometry. Moreover, optical transmission and transmission electron micrographs (TEM), diametral tensile stress (DTS), and confocal Raman spectroscopy was performed to determine the degree of conversion (DC) at 1.0, 1.4, and 2.0 mW/cm light intensities. It was found that the optimal conditions were at 0.0208 wt% AuNPs concentration and 1.4 mW/cm light intensity at which the refractive index change, DTS, and DC data were all maximal. The study confirmed that AuNPs are applicable to improve the polymerization efficiency of dental composite resin.

摘要

金纳米颗粒（AuNPs）在特定光频率照射下会表现出表面等离子体共振（SPR）。SPR还会导致产热，使周围环境温度升高，从而影响聚合反应。本研究旨在探究AuNPs对基于二甲基丙烯酸酯的光聚合体系的SPR效应。所测试的复合材料设计为使聚合所需的光照与等离子体效应相重叠。将5纳米大小的十二烷硫醇包覆的AuNPs以不同浓度应用于基质中，并用绿光（λ = 532纳米）照射，其中光引发剂Irgacure 784也会吸收该光。通过表面等离子体共振成像（SPRi）并辅以椭偏仪来研究等离子体效应引起的折射率变化。此外，还进行了光透射和透射电子显微镜（TEM）、径向拉伸应力（DTS）以及共焦拉曼光谱分析，以确定在1.0、1.4和2.0毫瓦/平方厘米光强下的转化率（DC）。结果发现，最佳条件是AuNPs浓度为0.0208重量%且光强为1.4毫瓦/平方厘米，此时折射率变化、DTS和DC数据均达到最大值。该研究证实AuNPs可用于提高牙科复合树脂的聚合效率。
