Simultaneous enhancements of mechanical and thermal properties of monomer cast nylon via kaolin modified by poly (ethylene glycol diglycidyl ether)

Monomer cast nylon was incorporated with different contents of kaolin, which is grafted with poly (ethylene glycol diglycidyl ether) via in-situ polymerization. The influence of treated-kaolin and kaolin contents on composites properties was studied. Treated-kaolin has a better effect on the properties of nylon than kaolin. Thermogravimetric analysis and Differential scanning calorimetry analysis show that that the feeding of kaolin improved thermal stability and crystallinity of nylon. The results indicate that using treated-kaolin as reinforcement, the composites displayed remarkable mechanical properties, the tensile strength and notched impact strength are 83.6 MPa and 4.46 MPa, respectively. The water absorption capacity of composites was greatly reduced by 50% with the feeding of kaolin.
