=2.5). A commercial organoclay, I34, was also used in LLDPE based nanocomposites to make a comparison. XRD and TEM analyses of the compounds prepared by DMDA and TBHP showed mixed nanocomposite morphologies consisting of partially intercalated and exfoliated layers. Young`s modulus and tensile strength of nanocomposites prepared with DMDA and TBHP showed generally higher values compared to those of neat LLDPE, while results were the highest in the composites prepared with commercial organoclay I34. Parallel disk rheometry was used as a supplementary technique to XRD, TEM and mechanical characterizations, and it was shown to be a sensitive tool in assessing the degree of dispersion of clay layers in the polymer matrix.

Texto completoThis work is divided into two parts: a papermaking part and a textile one. In the first part, new and if possible ‘green’ products, which can improve paper wet-strength, have been designed. For this purpose, unsaturated quaternary ammonium salts (SAQs), many of them unpublished so far, were synthesized. These salts were then polymerized using a microwave reactor. The resulting (co)polymers are cationic, water-soluble and amphiphilic. We demonstrated that papers, once treated by an amphiphilic N,N-diallyl-pyrrolidinium-based copolymer and carboxymethylcellulose (CMC) via a bi-layer treatment, were endowed with an obvious hydrophobic character. Moreover, other copolymers synthesized from N,N-diallyl-3-hydroxy-azetidinium (CDAHA) were able to impart to paper sheet a wet-strength comparable to that usually provided by polyamide-amine-epichlorohydrin (PAE) resins. The second part of the present work is dedicated to the development of an optimal anti-wrinkle recipe for cotton fabrics based on polycarboxylic acids. This recipe should be ideally efficient, cheap and eco-friendly. For that goal, citric acid (CA) was used as the active medium of the recipe that was based on 5% aq AC (w/w) solution and a catalyst mixture: sodium hypophosphite / cyanamide (1 eq, 0.75, 0.25). Temperature and heating duration was respectively optimized at 170°C and 90 s. Resulting crease-resistant properties can be estimated at best to good. However, such an anti-wrinkle treatment causes a degradation of both tensile strength and whiteness index. Cottons treated with the optimum recipe and other recipes were characterized by different analytical methods. Data showed that esterification reaction of cellulose with AC occurs mainly in the cell wall and does not affect the yarn surface. In addition, polymerization degree of treated cellulose was reduced of 60% in accordance with already measured mechanical properties

In this study, two quaternary ammonium iodide containing conjugated polyelectrolytes (MPCF-E, MPCFO-E) were synthesized and developed for dye-sensitized solar cells (DSSCs) application. The conjugated polyelectrolytes MPCF-E and MPCFO-E were synthesized via copolymerizating of quaternary ammonium iodide containing carbazole monomers with the n-alkyl chain or ethoxycarbonyl containing fluorene monomer, respectivity. Two conjugated polymer electrolytes were incoporated into the PEO based gel-type electrolytes for the enhancement of the ionic conductivity. The N719 dye based DSSCs were fabricated from these conjugated polymer electrolytes based gel-type electrolytes. The maximum overall conversion efficiency of 1.17%, open circuit voltage of 0.55V, short-circuit current of 4.97 mA/cm2, fill factor of 0.43. were observed for the DSSC based on 0.5 wt. % MPCFO-E doped PEO gel electrolyte. Better stability was observed for the MPCFO-E doped PEO electrolyte based DSSC as compared to the PEO based electrolyte based DSSC.
