Nylon 610/graphene oxide composites prepared by in-situ interfacial polymerization

Area of Science:

• Materials Science
• Polymer Chemistry
• Nanocomposites

Background:

• Graphene oxide (GO) is a promising material for composite fabrication.
• Improving the interfacial adhesion between GO and polymer matrices is crucial for enhanced properties.

Purpose of the Study:

• To fabricate nylon 610/graphene oxide (GO) composites with enhanced interfacial adhesion.
• To investigate the effect of grafting nylon 610 onto GO on the composite's thermal properties.

Main Methods:

• In-situ interfacial polymerization using acyl chloride-functionalized GO.
• Synthesis of GO-grafted nylon 610 (GO-g-nylon 610) via condensation reaction.
• Fabrication of nylon 610/GO and nylon 610/GO-g-nylon 610 composites.

Main Results:

• Nylon 610/GO-g-nylon 610 composites exhibited enhanced thermal properties with increasing GO-g-nylon 610 content.
• A 10% GO-g-nylon 610 composite showed a 72.2 °C increase in degradation temperature and a 36.9% increase in thermal conductivity.
• The crystallinity of the composite decreased due to strong interfacial adhesion hindering polymer chain mobility.

Conclusions:

• Grafting nylon 610 onto GO significantly improves the interfacial adhesion in nylon 610/GO composites.
• The developed nylon 610/GO-g-nylon 610 composites demonstrate superior thermal performance for advanced applications.
