Combining additive manufacturing with energetic ferroelectric materials for guiding chemical energy release
Molecular energetic ferroelectric crystals are chemical energy materials with external stimuli-dependent energy release. Researchers now report the controlled chemical energy release from spatially programmed molecular energetic ferroelectric crystals. Such stimuli-controlled metamaterials (in this case, energetic ferroelectrics), could potentially provide a pathway towards the controlled release of chemical energy and its conversion to electric energy or thermal energy for use, for instance, in energy conversion systems, energetic materials, and thermal conductors.
