Direct Ink Writing 3D Printing of High Graphite Loading Polybenzoxazine Composite

Polymer Composites, EarlyView.
Graphite reinforced benzoxazine can be directly printed and crosslinked with help of an inert power support. This allows the graphite particle to form temporary scaffold and the printed shape to be preserved. ABSTRACT Polybenzoxazine is a class of high‐performance thermoset that can be reinforced with graphite to gain great thermal stability, chemical ...
