Properties of epoxy nanoclay system based on diaminodiphenyl sulfone and diglycidyl ether of bisphenol f: influence of post cure and structure of amine and epoxy
Abstract
Materials were prepared with Cloisite 30B, diglycidyl ether of bisphenol F and diaminodiphenyl sulfone (DDS) to investigate the relationship between exfoliation and property enhancement. A higher level of exfoliation was found with 4,4-DDS than in the material cured with 3,3-DDS. The material with 4,4-DDS that exhibited a higher degree of exfoliation also resulted in larger improvements in physical properties with nanoclay. Increasing the ratio of trifunctional to difunctional epoxy led to a significant decrease in the level of clay dispersion. Increasing the ratio of trifunctional epoxy in the nanocomposite also caused a decrease in Tg with the addition of nanoclay. However, an increase in Tg with increasing clay loadings was detected in samples with a higher degree of exfoliation, with only difunctional epoxy. Similar behaviour was found for samples with and without a post cure. Excessive post cure led to a decrease in thermal stability in Cloisite 30B-containing samples.
