Resumen:
Polybenzoxazines are considered a new type of thermosetting phenolic resins whose synthesis is quite simple. Polybenzoxazines present unique features that make them promising candidates for various industrial applications including electronics, aerospace, composites, coatings, adhesives, and encapsulants manufacturing. Two new benzoxazine materials have been synthesized and polymerized from the renewable diphenolic acid. The diphenolic acid-based benzoxazine (DPA-Bz) enables the preparation of rigid foams as well as flame retardant counterparts through a self-induced foaming process. For the methylester derivative benzoxazine (MDP-Bz), fiberglass reinforced materials were obtained with flame retardancy properties. Moreover, by adding neat carbon nanotubes, nanocomposite materials were prepared with low percolation threshold and improved thermal and fire properties.
