Item Biotreatment on cellulose fluff pulp : quaternary ammonium salts finish and grafting with β -cyclodextrin(2009) Ghemati, Djamila; Aliouche, Djamel; Oudia, Atika; Lamouri, SaadFor its potential performances to be expanded, cellulose needs to be processed in different ways. Therefore, an object of the present work was to provide a chemical modification of cellulose through: a specific finish with two quaternary ammonium salts (namely Aliquat 336 and Aliquat 1529, respectively). Chemical grafting of β -cyclodextrin derivative ( β -CD) onto fibers followed by the inclusion of benzoic acid in the grafted CD cavities as a probe chemical. Physicochemical properties and performances of the untreated and treated fibers have been determined with infrared spectra, microscopy, swelling measurements, antimicrobial finishing tests, and dye adsorption. Our results show that cellulose fibers can be efficiently modified with no significant changes in its structural and surface properties; the treated fibers show an attractive behavior in swelling, dye adsorption and antibacterial activityItem Thermoelectrical characterization of new material based on PANI/zeolite HY composite, used for the detection of carbon dioxide(Nature Publishing Group, 2013) Safidine, Zitouni; Ghebache, Zahra; Lamouri, Saad
