摘要: Polystyrene-block-poly(ethylene oxide) (PS-b-PEO) diblock copolymer was synthesized and incorporated into novolac resin to obtain the nanostructured phenolic thermosets with hexamethylenetetramine (HMTA) as curing agent. The morphology of were investigated by means atomic force microscopy (AFM) small-angle X-ray scattering (SAXS). It found that long-ranged ordered nanostructures formed after before reaction. In views miscibility subchains phenol−formaldehyde resins reaction, it judged formation followed mechanism self-assembly. thermosetting blends, PEO subchain miscible cuing Fourier transform infrared (FTIR) spectroscopy showed reaction significantly weakened intermolecular hydrogen-bonding interactions between matrix s...
