Both of them were produced by electrical explosion of wire and coated with different chemical substances: stearic acid, palmitic acid, trihydroperfluoroundecylalcohol , and ester from esterification of trihydroperfluoroundecylalcohol with maleic anhydride. After their physical characterization (SEM, TEM, BET surface area, C % , DSC and TGA), the nano sized powders were added to a reference HTPB solid fuel for hybrid propulsion and burnt in a 2D radial burner to evaluate the effects on regression rate. Coatings play an important role on ballistics: with respect to pure HTPB, most of the investigated formulations exhibits increases of regression rate.
