Carbon Nanotubes Highly Dispersed by Eco-Friendly Alkyl Chain-Bridged Lignin-Based Polymer and Its Properties
Researchers at Dongguan University of Technology have successfully developed a new method to disperse carbon nanotubes (CNTs) using an eco-friendly alkyl chain-bridged lignin polymer. This breakthrough has significant implications for the application of CNTs as electrode materials and widens their potential uses. The study, published in ACS Omega, reveals that the dispersion efficiency of CNT suspensions was greatly improved using the lignin-based polymer, and the resulting CNT products exhibited enhanced electrochemical performance and thermal stability.
Key Takeaways:
- The research team used an alkyl chain-bridged lignin polymer to disperse CNT suspensions, resulting in a highly dispersed and stable CNT product.
- The CNT products exhibited improved electrochemical performance, with a significant reduction in electrochemical impedance and an increase in redox peak.
- The thermal stability of the CNT products was also improved, with a residual mass of up to 97% at 250 degrees C.
- The study concluded that the lignin-based polymer successfully addressed the limitations of CNTs and facilitated their application as electrode materials.
- The research has opened up new possibilities for the use of CNTs in various applications, including energy storage and conversion devices.
- The study was supported by the Basic and Applied Basic Research Foundation of Guangdong Province and the Doctoral Research Initiation Foundation of Dongguan University of Technology.
- The research team consisted of Nanlong Hong, Jinrong Huang, Quanyou Li, Yanjun Chen, and Qingui Chen from Dongguan University of Technology.
Statistics:
- The CNT suspension was dispersed to a high degree using the alkyl chain-bridged lignin polymer, with a dispersity index of up to 10,000.
- The lactate yield of the CNT product was increased by 25% when the lignin-based polymer was used.
- The oxidation potential of the CNT product decreased slightly with the increase of lignin polymer dosage, indicating improved electrochemical performance.
- The CNT products exhibited a residual mass of up to 97% at 250 degrees C, indicating excellent thermal stability.
