Abstract
Fluorine-containing polymers are one of the most useful materials among various polymers. In this study, we have developed synthesis methods for fluorine-containing polymers through sequential and chain polymerization based on the generation of perfluoroalkyl radicals by photoirradiation halogen bonding of perfluoroalkyl iodide and amines. In sequential polymerization, fluoroalkyl-alkyl-alternating polymers were synthesized by the polyaddition of diene and diiodoperfluoroalkane. In chain polymerization, polymers with perfluoroalkyl terminals were synthesized by polymerization of general-purpose monomers, with perfluoroalkyl iodide as the initiating species. Block polymers were also synthesized by successive chain polymerization to the polyaddition product.

Abstract
In this study, concentrated polymer brush-modified cellulose nanofibers (CNFs) with different fiber lengths were used for the flocculation of cells for systematically studying the mechanism of this unique cellular flocculation based on colloidal flocculation theory. Concentrated poly(p-styrenesulfonic acid sodium salt) brush-grafted CNF (CNF-PSSNa) with different fiber lengths were cultured with three different cell types to examine their influence on floc (cell clusters formed by cellular flocculation) characteristics. The floc size and survival rate could be controlled by modifying the CNF-PSSNa fiber lengths. The three cell types showed the same flocculation tendency after culture, indicating the applicability of the method in different cell lines. After 2 weeks of culture, CNF-PSSNa increased the specific expression of hepatocytes compared to the two-dimensional cell culture. Thus, owing to its wide applicability, high cell viability, and ability to control cell size and improve cell function, this technology could be used as a new three-dimensional cell culture method.

Abstract
Spontaneous polarization P of mixed polymer crystals based on β poly(vinylidene fluoride) (PVDF, -CH2-CF2-) and 2,3,3,3-tetrafluoropropene (TFP, -CH2-CF(CF3)-) was evaluated for β-PVDF/iso-PTFP, β-PVDF/P(VDF-alt-iso-TFP) and β-PVDF/syndio-PTFP. A plane-wave-based density-functional theory (DFT) approach, combined with the Modern Theory of Polarization formalism utilizing maximally-localized Wannier functions for calculating P, indicates that all systems exhibit similarly high or even slightly larger polarization than that of perfectly crystalline β-PVDF (0.18 C m-2). These properties stem from the substantial dipole moment of the TFP unit, which is estimated to be ∼2.3 D in an isolated chain, but is enhanced to ∼2.8 D in the crystal.
