Soft electroactive materials: polymers, oligomers, molecular crystals and cocrystals

Only a few pictures here for now:

beta-pvdf.alt
Figure: The structure of the crystalline phase of β-PVDF. The polar-covalent nature of the F-C and C-H bonds leads to polarization in the VDF monomer, directed perpendicular to the carbon backbone; dF-C and dC-H are the bond-dipole moments.

 

pvdf_chain_wfc_lettered
Figure: Maximally Localized Wannier Functions (MLWFs) and their charge centers computed for an isolated infinite β-PVDF chain. (a) Diamonds mark the positions of the MLWF charge centers on the chain. (b–d) Typical MLWFs localized on carbon-carbon, carbon-fluorine, and carbon-hydrogen bonds, respectively.
