1. A composite comprising:
a thermoplastic polymer matrix synthesized in-situ from a monomer mixture or a precursor polymer in the presence of a dispersion of a piezoelectric ceramic filler and an ionic additive and in absence of an organic solvent, the monomer mixture or the precursor polymer comprising from about 70 weight percent (wt. %) to about 95 wt. % of an alkyl methacrylate and from about 5 wt. % to about 30 wt. % of a hydroxyalkyl methacrylate based on the total weight of the monomer mixture or the precursor polymer.
