Le premier chapitre tentera de passer en revue ce qui peut distinguer, du point de vu de sa conductivité, un isolant réel, utilisé dans des conditions industrielles simples - par exemple l’isolation d’un câble de transport d’énergie en continu – de l’isolant parfait, ne présentant strictement aucune conduction dans un champ appliqué constant. Ainsi, les différentes théories sur la conduction en régime permanent et transitoire à l’interface et dans le volume, seront rappelées. Le second chapitre est consacré à la description,d’une part de l’échantillon utilisé, et qui nous a été fourni par la firme de fabrication Rhône Poulenc, et d’autre part, du dispositif expérimental spécialement conçu pour la mesure des très faibles courants sous haute tension. La difficulté expérimentale de ce type de mesure, montre bien que ces matériaux sont proches en vu des moyens de mesure actuels, des isolants parfaits. Les résultats de mesure de courants, pour des champs électriques compris entre 24 et 72 MV/m et cela dans une plage de température allant de 60 à 140°C, feront l’objet du troisième chapitre. Dans le dernier chapitre un modèle théorique basé sur la coexistence de deux mécanismes, l’un d’origine dipolaire et l’autre lié à l’injection à l’interface électrode/ isolant, a été proposé. La simulation de ces courants par résolution numérique des équations qui les gouvernent, a été effectuée en fonction des paramètres tels que la mobilité, le coefficient d’injection, le temps de relaxation ... etc. Une comparaison entre l’expérience et le modèle nous permettra de déduire le profil du champ électrique et la répartition de la charge d’espace dans tout le matériau.

يتزايد الاهتمام العالمي بقضايا البيئة و الوعي بحقيقتها، و ارتباطها الوثيق بالتنمية المستدامة، التي تمثل اليوم مطلبا أساسيا لتحقيق العدالة في توزيع مكاسب التنمية و الثروة بين شعوب الأرض و أجيالها المتعاقبة. و تحقيق هذه التنمية أصبح يتطلب أكثر فأكثر الاهتمام بالمسائل الاجتماعية و البيئية للحد من المخاطر التي تواجه النمو الاقتصادي و التنمية. و باعتبار الطاقة كأحد مقومات هذا النمو، فقد أصبحت تشكل إحدى العقبات التي تواجه استدامة التنمية، خاصة فيما يتعلق بالبعد البيئي، حيث يعتبر النموذج الحالي لإنتاج و استهلاك الطاقة في العالم، و الذي يعتمد أساسا على موارد غير متجددة وملوثة للبيئة، نموذجا غير مستدام، كما أن مستويات الكفاءة في إنتاج الطاقة و استهلاكها، لم تصل بعد و بدرجات متفاوتة إلى المستويات المطلوبة. لذلك أصبح من الضروري إدماج البعد البيئي في إطار السياسات الطاقوية، و البحث عن نموذج طاقوي مستدام، يكفل استدامة التنمية، مع الأخذ بعين الاعتبار القيود البيئية، و حقوق الأجيال اللاحقة من هذه الموارد.

AbstractThe United States of America (U.S.A) presented itself as the worldwide power whichinterfered in the internal affairs of many countries such as Iran. Iran was considered as a threatto the international security due to its enrichment of the nuclear program, this made the USadopt several policies for limiting Iran’s nuclear capabilities. The current thesis presents acomprehensive investigation and analysis about the bilateral relationship between the US andIran. The purpose of this study is to analyze the foreign policy adopted by Barack Obamatowards Iran, examine the effectiveness and the outcomes of his policy, and compare hispolicy towards Iran with some previous president’s policies. This research uses the historicaland analytical approaches for collecting and analyzing data. The study findings revealed thatObama adopted some strategies that focused primarily on imposing political and economicsanctions against Iran, but later on he shifted to the strategy of negotiations and diplomacy toresolve the conflict. In addition, the study indicated that Obama could elaborate a directengagement between U.S and Iran that made the relation between the two countries better;thanks to the “Joint Comprehensive Plan of Action”, which legitimized the use of the nuclearweapons only in peaceful conditions. Moreover, the study revealed that the policy of Obamawhich relied also on the power of engagement and negotiations was better compared toClinton and Bush’s policies; this is due to the fact that the previous policies were moreconfrontational.

The systems which are the subject of the investigation, the chemically crosslinked copolymers of the"isobornyl acrylate-co-isobutyl acrylate" type (IBOA-co-IsoBA), were prepared byphotopolymerization / crosslinking under UV-visible radiation of the two monomers. IBOA and IsoBAin the presence of a di-functional crosslinking agent and a photoinitiator. In this work the thermaland mechanical properties were studied by differential scanning calorimetry (DSC), dynamicmechanical analysis (DMA) and thermogravimetric analysis (TGA).We have found by calorimetric analysis (DSC) that the modification of the concentration ofcrosslinking agent, the amount of monomers, and the speed of the heating ramp affect, in particular,the glass transition temperature Tg: an increase of these parameters causes an increase in the glasstransition temperature of the copolymer. Thermogravimetric analysis by (TGA) shows that thedegradation of the copolymer occurs in two stages, and that the increase of the amount of IsoBAdecreases the degradation temperature of the copolymer. The study of copolymers of type (IBA-co-IsoBA) by DMA was undertaken according to the frequency and the temperature, in order toevaluate the modulus of elasticity (E ') and of loss (E' ') . A master curve has been obtained using thetime-temperature superposition principle. Modeling of the mechanical relaxations was carried out byapplying the models of Arrhenius, Cole-Cole, WLF and VFT (Vogel Fulcher Tamman).
