Structure of P3HT in the solid state
(Wiley-Blackwell, 2013-09-15)
Poly(3-hexylthiophene) (P3HT) is a polymer widely used in organic photovoltaic devices. Discrepancies in information exist in the literature about its morphological structure in solution and in the solid state. This work ...
Films from resistant starch-pectin dispersions intended for colonic drug delivery
(2014-01-01)
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...
Polaronic ferromagnetism in conducting polymers
(2001-12-01)
Ferromagnetic behavior at room temperature is reported in metal-free-conducting polymer samples of poly(3-methylthiophene) doped with ClO 4 -. Magnetic moments associated with spin 1/2 positive polarons are possibly ...
Ecotoxicity Evaluation of the Biodegradable Polymers PLA, PBAT and its Blends Using Allium cepa as Test Organism
(2018-03-01)
Biodegradable polymers are considered a feasible option to minimize the environment impacts of high disposal of solid waste. Nevertheless, environmental safety of these materials is a few explored issue. In this context, ...
A selective conductive polymer-based sensor for volatile halogenated organic compounds (VHOC)
(ELSEVIER SCIENCE SA, 2008)
A novel poly(p-xylylene), PPX, derivative bearing alkoxyphenyl side groups was electrochemically synthesized in 87% yield. The polymer, poly(4`-hexyloxy-2,5-biphenyleneethylene) (PHBPE), presented a fraction (92%) soluble ...
Glossary of terms relating to electronic, photonic and magnetic properties of polymers (IUPAC Recommendations 2021)
(2022-01-01)
These recommendations are specifically for polymers and polymer systems showing a significant response to an electromagnetic field or one of its components (electric field or magnetic field), i.e., for electromagnetic-fi ...
Polymer with tetrazolic pendant groups. Interaction between the heterocyclic groups and heavy metals
(Research Trends, 2013-03)
The interaction between a polymer with tetrazolic pendant groups, and heavy metals (Pb(II) or Cd(II)) was studied. The product resulting from these interactions was characterized by Fourier transform infrared spectroscopy, ...
