Advanced thermosets for high performance coatings, adhesives and composites

Thermosets include a broad range of materials such as epoxies, phenolics, unsaturated polyesters, vinyl esters and bismaleimide resins. In general, thermosets are known for their good adhesion, high chemical and heat resistance, excellent mechanical and electrical insulating properties. However, they are generally brittle materials due to their crosslinked nature. The research in this area aims at designing block copolymer-based nanostructured thermosets with an effort to develop novel advanced tough thermoset materials with superior mechanical properties and optical clarity.


Hierarchical nanostructures

an image of hierarchical nanostructures
Hierarchical nanostructures were observed in cured epoxy resin/block copolymer blends. Spherical micelles of diameter ~10 nm are dispersed throughout the resin phase which is composed of a harder epoxy-rich region and a softer copolymer-rich region on the 100 nm scale as shown in AFM phase image below. The larger structures are aggregates of smaller spherical or wormlike micelles.

Nanoporous thermosets

We use ozonolysis to produce nanoporous epoxy thermosets. Ozone treatment was employed to create nanoporosity in nanostructured epoxy/PI-P4VP blends via selective removal of the PI microphase, leading to nanoporous epoxy thermosets. Multiscale phase separation with a distinctly different morphology was observed at the air/material interface due to the interfacial effects, whereas only uniform microphase separated morphology at the nanoscale was found in the bulk of the blend of the blend.
