摘要: The rheological properties and mechanical of percolated cyanate ester monomer/layered silicate mixtures are reported. A number different cation exchanged montmorillonites were examined in an effort to achieve maximal montmorillonite delamination. dispersion throughout the a with phenylated ammonium cations (2MBHT MMT) results formation network. rheology this network undergoes viscous liquid elastic solid transition at 4 wt% montmorillonite. percolation significant improvement crack resistance (80%) without sacrifice flexural strength.
