Graphite Layer Nano-composites with Polyurethane Matrix

Czajka M., Shanks R.A., RMIT University, AU

The aim was to prepare expanded graphite oxide (GO, Graftech Inc.) and disperse it in a polyol (poly(oxypropylene glyceride), Dow Chemicals) using ultrasonication. The dispersion was polymerized and crosslinked with methane 4,4’-diphenyldiisocyanate to form a [...]
