Well-defined copolymers based on poly(vinylidene fluoride): From preparation and phase separation to application

Abstract

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 other monomers leads to a wide variety of products with modified or improved properties. Besides commercially available fluorinated random copolymers, well-defined block-, graft, and alternating copolymers based on PVDF received more attention in recent years. PVDF-containing block copolymers that may selfassemble into well-ordered morphologies are of particular interest, being potential precursors for functional nanostructured materials applicable in membranes and electronics. This Highlight provides an overview of the routes developed towards these materials via conventional and controlled polymerization techniques. In addition, it discusses their nanoscopic phase behavior and current and potential applications.

Organometallic‐Mediated Alternating Radical Copolymerization of tert‐Butyl‐2‐Trifluoromethacrylate with Vinyl Acetate and Synthesis of Block Copolymers Thereof

“…Indeed, Daikin was the first company to develop such materials over 35 years ago, leading to the industrial scale production of segmented thermoplastic elastomers . Since these pioneering works, interest in fluorinated block copolymers has surged in the last decade. This led to the synthesis of a variety of fluorinated block copolymers prepared using telomerization, conventional radical polymerization from functionalized initiators, click chemistry, and using different RDRP techniques: iodine transfer polymerization (ITP), photoinitiated ITP, reversible addition fragmentation chain transfer (RAFT) polymerization, and atom transfer radical polymerization (ATRP) .…”

Iodine‐transfer polymerization and CuAAC “click” chemistry: A versatile approach toward poly(vinylidene fluoride)‐based amphiphilic triblock terpolymers

“…A variety of PVDF‐based triblock copolymers have been prepared via a CuAAC reaction . In regard to PVDF‐based triblock copolymers, the data are very limited and only reports on the ABA triblock copolymer system [where A: PS, poly(N‐isopropylacrylamide), poly( tert ‐butyl acrylate) and poly(lactic acid) and B:PVDF] exist . Interestingly, ABC triblock terpolymers can coordinate into a greater variety of ordered structures than the AB or ABA analogs …”
