| 摘 要： | 为了在分子水平上对增强体表面、界面相进行有目的的控制,采用一种新的碳纤维表面改性方法-分子自组装.表面增强拉曼散射光谱(SERS)分析证实了一系列不同链长的羟基取代烷基硫醇化学吸附在镀银的碳纤维表面,并形成了竖直取向的自组装膜结构.微脱粘界面性能测试表明,经组装改性后的碳纤维和环氧复合后界面粘结强度得到了不同程度的提高,揭示了界面区域组装分子链长和界面性能的关系. |
| 关 键 词： | 碳纤维 环氧 复合材料 分子自组装 硫醇 表面增强拉曼光谱 |

| Abstract: | In order to gain a controlled interface between carbon fiber and epoxy matrix at molecular level,a new method based on the molecular self-assembly was proposed for the carbon fiber surface modification.The surface-enhanced Raman scattering spectroscopy(SERS) analysis verified that a series of hydroxyl-substituted alkanethiols with different alkyl chain lengths chemisorbed onto the Ag-plated carbon fibers and formed a stand-up phase.The microbond testing results showed that the interfacial bonding strengths of modified carbon fiber/epoxy composites were improved.The relationship between alkyl chain length and interfacial properties was revealed. |
| Keywords: | carbon fiber epoxy composites molecular self-assembly thiols SERS |
