PROPOSITIONS belonging to the PhD thesis
Tuning the crystalline phases of poly(vinylidene fluoride) for
capacitive energy storage applications
1. Nanometer sized well-isolated poly(vinylidene fluoride) β-crystals are desirable for capacitive energy storage applications. (Chapter 1 and Chapter 2).
2. Block copolymer self-assembly is a useful tool to gain fundamental insights in the crystallization properties of polymers. (Chapter 2 and Chapter 3). 3. The Curie transition temperature of fluorinated polymers is next to the
polymer composition, crystallite size and crystal lattice spacing dependent on the cooperative movement of polymer chains surrounding the ferroelectric crystals. (Chapter 3 and Chapter 6).
4. Poly(vinylidenefluoride-co-vinyl alcohol) copolymers are a potential safe and cheap alternative for poly(vinylidene fluoride-co-trifluoroethylene) copolymers (Chapter 4).
5. The introduction of hydroxyl functional groups in fluorinated co-and terpolymer chains gives easy accessible crosslinking sites for tuning the crystallization and electroactive properties (Chapter 5 and Chapter 6). 6. Expanding the size of crystal lattices is not a prerequisite to obtain relaxor
ferroelectric behavior in fluorinated polymers (Chapter 6). Niels Meereboer
