Performance improvement of polysulfone ultrafiltration membrane has been achieved by blending with PANI-NFs [457]. Conducting blends of nanostruetured PANI and PANI-clay nanocomposites with ethylene vinyl acetate as host matrix have been prepared [458]. A new conducting hybrid biocompatible composite material of PANI-NFs well dispersed in a collagen matrix was fabricated with various PANI-NFs/eoUagen ratios [459]. PANI-NFs doped by protonic acids can be efficiently dispersed in vinylidene fluoride-trifluoroethylene copolymers [460]. Fabrication of MWCNTs/PANI-NF nanocomposites via electrostatic adsorption in aqueous colloids has been reported [143]. A PANI-NFs/ carbon paste electrode was prepared via dopping PANI-NFs into the carbon paste [461]. [Pg.65]

Electrical Stimuli. Electrically active materials have also been used to encourage tissue growth. The use of piezoelectric materials made of vinyUdene fluoride-trifluoroethylene copolymer [P(VDF-TrFE)] enhanced peripheral nerve regeneration in vivo (Fine et al., 1991), and when PC12 cells were cultured on oxidized polypyrrole, the application of an electrical stimulus resulted in enhanced neurite extension (Schmidt et al., 1997), as shown in Fig. 16.3. Implant vascularization was enhanced when bilayer films of polypyrrole-hyaluronic acid and polypyrrole-poly(styrenesulfonate) were implanted subcutaneously (Collier et al., 2000). These types of electrical stimuli can be used in conjunction with a biomaterial to promote tissue regrowth. [Pg.370]

The phase separation process of blends has been studied by a number of researchers. Chaleat et al. investigated the phase separation of plasticized starch/ PVA blends (Chaleat 2012) blends of vinylidene fluoride/trifluoroethylene copolymer and poly(l, 4-butylene adipate) was studied by Kap Jin Kim and K5m (Kim and Kyu 1999). Fully biodegradable blends of poly(butylene succinate) and poly (butylene carbonate) and its phase behavior were studied by Wang (2012). [Pg.1086]

It is important in some applications that the polymer does not embrittle outside a certain temperature range. Engineering plastics, which do not embrittle include LDPE, HDPE, PA, PTFE, ethylene-trifluoroethylene copolymer, fluorinated ethylene-propylene copolymer and silicones. PP, epoxy resins and polymethyl pentene are all subject to embrittlement. [Pg.62]

The results for the trifluoroethylene copolymer suggests that structural isomerism should indeed be detectable by ESCA. In view of this, deconvolutions may be attempted for the trifluoro- and chlorotrifluoro-ethylene copolymers using five individual peaks with lineshape and linewidth corresponding to that for the p3 Cis levels. The five peaks in each case corresponding to four CP2 and CFX carbons, (in two pairs corresponding to the two distinct modes of bonding) and only one for the CP3 carbon. [Pg.295]

The improvement in energy harvesting is not achieved by all nanocomposites. Reduction in stiffness can lower the energy power, as in the case of electrospinning vinylidene fluoride—trifluoroethylene copolymer with a ceramic filler of BaTiOa (Nunes-Pereira et al., 2013). Nanopiezoelectric fillers of 10-nm size have higher output than larger fillers of 100—500 nm. [Pg.415]

Investigations in the 1970s were extended to include copolymers of vinylidene fluoride (VDF) with related fluorinated vinyl monomers vinyl fluoride (VF), trifluoroethylene (TrFE) and tetrafluoroethylene (TeFE) [7, 8]. The latter two copolymers were found to crystallize into polar form without the stretching stage required by PVDF. This facilitates processing, and thus offers a wider range of potential device structures. Research in the 1980s has therefore focused on the ferroelectric behaviour and piezoelectric activity of vinylidene fluoride-trifluoroethylene copolymers. [Pg.188]
