Studies on properties of polyaniline-dodecylbenzene sulfonic acid composite films synthesized using different oxidants

Two types of nano composite were obtained by in situ chemical method in polyaniline (PANI)/dodecylbenzenesulfonic acid (DBSA) system depending on the use of either ammonium persulfate (APS) or ferric chloride (FeCl 3 ) as the oxidant. In order to study the difference of the two composites in the surface characteristics, thermal stability, and electric properties, the composite films were studied by transmission electron microscopy (TEM), Xray diffraction (XRD), thermogravimetric analysis (TGA), and temperature dependent DC electrical conductivity. The results revealed a large difference in the surface morphology, thermal stability, and the microstructure properties between the two composites, and these differences were considered responsible for the molecular order and conductivity.

“…Lithographic and etching techniques, in principle, make it possible to engineer structures and defects in detail, as well as to attain sufficient dielectric contrast, but achievement of small structures down to the optical length scale is challenging. On the other hand, spontaneous assemblies allow formation of small enough structures based on colloids [5,6], synthetic opals [7][8][9][10][11], inverted opals [7,[12][13][14][15][16], and block copolymers [17][18][19][20][21][22]. In such cases, although the organization leads to a welldefined local order, it is nontrivial to achieve perfectly ora e-mail: g.ten.Brinke@chem.rug.nl b e-mail: Olli.Ikkala@hut.fi dered structures over the macroscopic length scale, which, in addition should contain carefully engineered defects for "light channels".…”

One-dimensional optical reflectors based on self-organization of polymeric comb-shaped supramolecules Kosonen, H; Valkama, S; Ruokolainen, J; Torkkeli, M; Serimaa, R; ten Brinke, G; Ikkala, O Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim.Downloaded from the University of Groningen/UMCG research database (Pure): http://www.rug.nl/research/portal. For technical reasons the number of authors shown on this cover page is limited to 10 maximum. Abstract. We demonstrate that complexation of dodecylbenzenesulphonic acid, DBSA, to a diblock copolymer of polystyrene-block-poly(4-vinylpyridine), PS-block-P4VP, leads to polymeric supramolecules PS-block-P4VP(DBSA)y (y = 1.0, 1.5, and 2.0), which self-organize with a particularly large lamellar periodicity in excess of 1000Å. The structures consist of alternating PS and P4VP(DBSA)y layers, where the latter contains smaller internal structure, probably lamellar. The DBSA side chains are bonded to the pyridines by protonation and hydrogen bonding and they effectively plasticize the material. In this way relatively well-developed structures are obtained even without annealing or macroscopic alignment. Transmission and reflectance measurements show that a relatively narrow and incomplete bandgap exists for supramolecules of high molecular weight block copolymer at ca. 460 nm.

Porous Polymer Membranes by Hard Templating – A Review

2017

View full text Add to dashboard Cite

Membranes are designed to bridge a precise separation process at the nanoscale with industrial applications running at cubic meters per hour. This review outlines materials applied in membrane production with a particular focus on polymers. Membrane performance and created value are directly linked to controlled pore formation. Their economic relevance has created a number of large companies and associated academic research at top institutions. The authors review, therefore, starts from well-established techniques applied in products and then moves on to evolving concepts from academia. Pore formation through hard templating is a versatile field for separation processes. A more detailed view is given on the two known concepts for nanopore formation, namely colloidal templates and random hard salt templating. A comparison between these two concepts underlines their relevance to combine a process specific separation with large scale manufacturing requirements (i.e., upscale possibility, flexible process control and environmental impact).
