A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)
Advanced Functional Materials, EarlyView.To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local
