环氧树脂(EP)的阻燃性和导热性能的优化,用于关键应用,如机械部件和电子封装,是一个重大挑战。这项研究介绍了一部小说,超声辅助自组装技术,以创建由碳纳米管和聚磷酸铵(CNT@APP)组成的双功能填料。这种方法,利用动态配体相互作用和战略溶剂选择,允许精确控制碳纳米管在APP表面上的组装和分布,将其与传统的混合方法区分开来。7.5重量的积分。%CNTs@APP10加入EP纳米复合材料可显著提高阻燃性,极限氧指数(LOI)值为31.8%,并达到UL-94V-0等级。此外,关键火灾危险指标,包括总放热(THR),总烟雾释放量(TSR),和CO产量(PCOY)的峰强度,大幅减少45.9%至77.5%。这种方法还导致了显著的3.6倍提高的焦炭产量,展示了其在传统混合技术上改变游戏规则的潜力。此外,尽管添加了最少的碳纳米管,热导率显著增强,增加了53%。这项研究为多功能EP纳米复合材料的开发提供了一种新的方法,提供广泛的应用潜力。
The optimization of flame retardancy and thermal conductivity in epoxy resin (EP), utilized in critical applications such as mechanical components and electronics packaging, is a significant challenge. This study introduces a novel, ultrasound-assisted self-assembly technique to create a dual-functional filler consisting of carbon nanotubes and ammonium polyphosphate (CNTs@APP). This method, leveraging dynamic ligand interactions and strategic solvent selection, allows for precise control over the assembly and distribution of CNTs on APP surfaces, distinguishing it from conventional blending approaches. The integration of 7.5 wt.% CNTs@APP10 into EP nanocomposites results in substantial improvements in flame retardancy, as evidenced by a limiting oxygen index (LOI) value of 31.8% and achievement of the UL-94 V-0 rating. Additionally, critical fire hazard indicators, including total heat release (THR), total smoke release (TSR), and the peak intensity of CO yield (PCOY), are significantly reduced by 45.9% to 77.5%. This method also leads to a remarkable 3.6-fold increase in char yield, demonstrating its game-changing potential over traditional blending techniques. Moreover, despite minimal CNTs addition, thermal conductivity is notably enhanced, showing a 53% increase. This study introduces a novel approach in the development of multifunctional EP nanocomposites, offering potential for wide range of applications.
