Summary on Grant Application Form
Intrinsic molecular chirality has a profound effect on the properties of polymer chains. Chiral polymer networks - elastic rubbers with a broken inversion symmetry - must exhibit a piezoelectric effect. Liquid crystal order added to the system makes the piezoelectric response very distinct and much stronger. The project aims, in collaboration with synthetic chemists, to confirm these theoretical expectations experimentally, establish a firm relation between the piezoelectric response and the molecular structure, and to study the non-linear piezoelectric effect in rubbers at large deformations.
