将石墨烯添加到正支剂粘合剂中会使它们的颜色变暗,并减少半透明度. 较高的石墨烯度会增加这些效应,但不会影响光固化过程中的转化程度.
科学领域:
- 材料科学 材料科学 材料科学
- 生物材料工程 生物材料工程
- 牙科材料 牙科材料
背景情况:
- ортодонтика固定支器对于维持治疗结果至关重要.
- 粘合性质,包括颜色和光学传输,可以影响临床应用和美学.
- 石墨烯是一种新型纳米材料,由于其独特的特性,在各种领域都有潜在的应用.
研究的目的:
- 为了研究不同度的石墨烯对正统牙粘合剂的颜色和光学传输的影响.
- 评估石墨烯添加对光固化过程中这些粘合剂转化程度的影响.
主要方法:
- 两种常见的正义牙粘合剂 (可包装和可流动复合材料) 用石墨烯 (0.01,0.05,0.1%重量%) 进行了修改.
- 使用色度计测量颜色和半透明度.
- 在光固化过程中量化了光学传输.
- 福利埃变换红外光谱学评估了转换的程度.
主要成果:
- 添加石墨烯显著暗化了粘合剂的颜色和减少了透光度,在较高度下,效果会加剧.
- 在0.1%重量%的石墨烯下,样品变得不透明.
- 在加入石墨烯时,没有观察到对转化程度的不良影响.
- 添加石墨烯减少了光学传输,效果与度成比例.
结论:
- 石墨烯纳入正粘合剂会改变其光学特性,主要是通过变暗颜色和减少半透明度.
- 粘合剂的转化程度不受石墨烯添加的影响.
- 石墨烯对光学传输的影响表明,在牙矯正中对光固化粘合剂系统的潜在考虑.

Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are formed faster owing to...
