Nevertheless, it typically possesses low piezoelectric performance, which severely limits its use for energy generation applications. Here, we demonstrate the synthesis of highly aligned, piezoelectric nylon-11 films through an energy-efficient (≈1-5 Wh), single-step platform that facilitates the electroacoustic coupling associated with MHz-order nanoscale vibrations during the crystallisation process. Uniquely, such coupling allows the simultaneous induction of (i) nylon's piezoelectric δ' -phase, (ii) long-range crystalline ordering, (iii) an ordered hydrogen-bonded network, and (iv) dipole alignment, which we directly probe usNature communicationsElectroacoustic alignment of robust and highly piezoelectric nylon-11 films.PMC12855992DP250100971Komljenovic RSherrell PCYeo LYEhrnst YRezk ARfalseElectroacoustic alignment of robust and highly piezoelectric nylon-11 films.Nylon-11-a common and widely used material, is a promising non-fluorinated piezoelectric polymer given its mechanical strength, chemical stability and elasticity.
