PCL and CNT composite dispersion
Fenómeno del problema
In PCL/CNT composites, carbon nanotubes agglomerate, dispersion is uneven, and performance improvement is limited.
Análisis de la causa
CNTs have high surface energy and easily agglomerate; PCL melt has high viscosity making dispersion difficult; insufficient mixing process; excessive CNT content; interfacial bonding.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①CNT surface modification; ②Dispersion process optimization (ultrasonication, ball milling, etc.); ③Content control (0.5% optimization); ④Interfacial agent; ⑤Dispersion detection.
Conclusión clave
Dispersion of PCL/CNT composites is the key to performance; 0.5% content is the research optimization point; testing verifies dispersion quality.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
