Líquidos iônicos como plastificantes em blendas de borracha nitrílica/polianilina

Química Nova, 2014
Two imidazolium-based ionic liquids (C4MIMTf2N and C4MIMBF4) were used to verify their influence on polyaniline (PANI) and nitrile rubber (NBR)/PANI blend properties and the vulcanization process. High conductivity values were observed for PANI-C4MIMTf2N

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

Macromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Macromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

From Collapse to Freezing in Random Heteropolymers

, 1997
We consider a two-letter self-avoiding (square) lattice heteropolymer model of N_H (out ofN) attracting sites. At zero temperature, permanent links are formed leading to collapse structures for any fraction rho_H=N_H/N. The average chain size scales as R

Direct evidence for electrostriction‐enhanced piezoelectricity in poly(vinylidene fluoride‐co‐trifluoroethylene) random copolymers

Responsive Materials, EarlyView.
Direct experimental evidence for electrostriction‐enhanced piezoelectricity is obtained for a quenched‐stretched‐annealed‐poled P(VDF‐TrFE) 52/48 mol.% random copolymer using time‐resolved small‐angle X‐ray scattering and wide‐angle X‐ray diffraction. Upon stretching up to 6% strain, the crystallinity (xc) increases 10% at the expense of the contents ...
