Self-assembly of poly(vinylidene fluoride)-based block copolymers:

from preparation and crystallization to composite fabrication

Research project

Poly(vinylidene fluoride) (PVDF) has reached the second largest production volume of fluoropolymers in recent years, and its popularity can be ascribed to high thermal stability and chemical inertness combined with its ferroelectric behavior. Copolymerization of vinylidene fluoride with comonomers leads to a wide variety of products with improved or modified properties. Besides commercially available fluorinated random copolymers, well-defined block-, graft and alternating copolymers based on PVDF received more attention in recent years. Block copolymers containing PVDF segments, able to self-assemble into well-ordered morphologies, are of particular interest, being potential precursors for novel functional nanostructured materials, applicable in membranes and electronics.

In order to explore such materials, we have successfully synthesized several PVDF-based block copolymers. For example, atom transfer radical polymerization (ATRP) of styrene (S), 4-vinyl pyridine (4VP) or tert-butyl methacrylate from PVDF telechelics lead to PS-b-PVDF-b-PS, P4VP-b-PVDF-b-P4VP and PtBMA-b-PVDF-b-PtBMA triblock copolymers. In addition, we have been able to produce PCL-b-PVDF-b-PCL, PLLA-b-PVDF-b-PLLA and P3HT-b-PVDF-b-P3HT (PCL = polycaprolactone, PLLA = poly(L-lactic acid), P3HT = poly(3-hexyl thiophene)) via a click chemistry approach, involving copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). The self-assembly of these block copolymers into ordered morphologies has been studied extensively, and crystallization appeared to play an important role in the structure formation. Nanoporous PVDF foam and PVDF/nickel nanocomposites were successfully prepared from PS-b-PVDF-b-PS and PVDF/PMAA/Ni nanocomposites from PtBMA-b-PVDF-b-PtBMA block copolymer precursors. Since the polar β-phase of PVDF has been observed, the foam and composites are suspected to exhibit ferroelectric properties. Combined with ferromagnetic nickel, the nanocomposite is a potential multiferroic material. The ferroelectric behavior of PVDF-based block copolymers and porous networks, as well as the multiferroic properties of PVDF/Ni nanohybrids, are currently explored in our laboratory.
