PolymérisationRésumé : La variation de certaines propriétés de matériaux, passe par une modification de leurs surfaces. Nous avons étudié l'influence de l'ajout de renforts sur les propriétés de surface de matériaux photopolymérisables à différentes matrices. Les matériaux obtenus sont soit micro ou nanocomposites, tout dépend de la taille des particules incorporées dans la matrice. Ces études révèlent une grande importance, vue que les résines photopolymérisables trouves des applications dans des domaines aussi variés que la microélectronique, les adhésifs, les peintures, les vernis ou les emballages. Dans cette perspective nous nous sommes intéressés à étudier les énergies de surface, l'effet barrière à l'eau, l'effet écran, l'effet matant et la dureté persoz. Les renforts incorporés sont du type lamellaire ou graphitique. Nous avons établi que l'incorporation, de particules d'argile, augmentait l'énergie de surface du composite alors que les renforts carbonés la faisaient diminuer. Nous avons démontré par ailleurs qu'on pouvait moduler l'effet barrière à l'eau en fonction de la nature et de la concentration du renfort. Les composites étudiés présentaient un effet matant nettement inférieur à celui des matrices.

TempératureIndex. décimale : 668.9 Polymères Résumé :
Most developing countries have hot climate, ordinary jobsites characterized by reduced of human resources, equipment and infrastructures. The objective of this article is to make an experimental study of the influence of the hot climate such as that of Algeria, on the different properties of concrete in the fresh state, such as excessive water evaporation from the concrete surface, increased demand for water, increased slump loss corresponding to additional water on job-site, higher plastic shrinkage cracking and difficulty in controlling air content. At the hardened state, we could mention a reduction of strength at 28 days, decreased durability resulting from cracking at long-term period.
To show the problems linked to concreting under these conditions and to present the appropriate solutions concrete or mortar can withstand the conditions in which it is implemented. Thus, negative effects caused principally by hot weather concreting motivated the choice of the such study. The research experimental work conditions in which the cementitious matrix was kept concerned two different environments, namely hot and dry climate conditions (t = 40°, h = 0%) alike the climate of the region of M'sila., and that of a medium with a hot and humid environment (t = 40°, h = 100%). The output of the investigation demonstrated the crucial role of the cure method in hot regions. The comparison of results for a reference concrete kept in air without any curing measures with two curing types simulating hot weather environment of the region M’sila was undertaken. These obtained outcome results were discussed based on the influence of climatic conditions to conclude procedures for hot weather concreting and suitable cure methods.Note de contenu : - MATERIALS

PolymérisationIndex. décimale : 667.9 Revêtements et enduits Résumé : Conductive polymers have been studied extensively because of their attractive physical properties, such as conductivity, luminescent performance, and dielectric property. Poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the most employed conductive polymers for applications, such as a buffer layer of organic electroluminescent devices, due to its high conductivity and electrical stability. In this study, we fabricated a conductive paper coated with PEDOT by direct polymerization onto a paper sheet. The conductive paper exhibited the electrical conductivity of 1.8 S/cm. Scanning electron microscopy images of the conductive paper showed two structures: thin polymer membranes attached to cellulose fibers at the surfaces, and thick polymer sheets extended through the void spaces between the fibers in the inner layers. Consequently, strong interactions between the PEDOT and the cellulose fibers enhanced mechanical properties of the conductive paper. Electron probe X-ray microanalysis (EPMA) revealed distribution elemental maps of carbon, oxygen, sulfur, chlorine, and iron on the conductive paper.
