目前发表的大多数碳纳米管分散协议依赖于不能规模化到工业水平的技术。这项工作展示了如何使用机械混合获得的多壁碳纳米管环氧树脂来获得具有良好力学性能的聚合物纳米复合材料。这项工作说明的机械分散方法很容易扩展到工业水平。由于复杂的运动场而产生的高剪切力产生了良好的和可重复的碳纳米管分散。我们测试了一种在不同碳纳米管重量载荷下具有良好基线力学特性的工业用环氧树脂。ASTM的拉伸和压缩测试表明，与原始树脂相比，杨氏模量和压缩强度都有所提高，从较低的wt%开始。对比振动试验表明，其减振能力有所提高。新型碳纳米管增强环氧树脂的机械性能优于市场平均竞争对手，是双组分环氧树脂市场的顶级产品之一。这种新的分散方法显示了碳纳米管在环氧树脂中的工业应用的巨大潜力。
The majority of currently published dispersion protocols of carbon nanotubes rely on techniques that are not scalable to an industrial level. This work shows how to obtain polymer nanocomposites with good mechanical characteristics using multi-walled carbon nanotubes epoxy resins obtained by mechanical mixing only. The mechanical dispersion method illustrated in this work is easily scalable to industrial level. The high shearing force due to the complex field of motion produces a good and reproducible carbon nanotube dispersion. We have tested an industrial epoxy matrix with good baseline mechanical characteristics at different carbon nanotube weight loads. ASTM-derived tensile and compressive tests show an increment in both Young’s modulus and compressive strength compared with the pristine resin from a starting low wt %. Comparative vibration tests show improvement in the damping capacity. The new carbon nanotube enhanced epoxy resin has superior mechanical proprieties compared to the market average competitor, and is among the top products in the bi-components epoxy resins market. The new dispersion method shows significant potential for the industrial use of CNTs in epoxy matrices.
