The development of flexible, wearable electronic devices is one of the future directions of technology development. Flexible conductive materials are important supporting materials for wearable electronic devices. Polymer has excellent flexibility; it is an important way to prepare flexible conductors from polymer-based conductive composites. In this paper, the research progress of polymer-based flexible conductive composites is summarized in terms of preparation and characterization methods. The key factors to realize flexible conductors are put forward, namely, the maintenance of excellent polymer elasticity and the realization of stability. The design and preparation of the extensible conductor with high-elasticity matrix and nanofiller are introduced in detail, and the problems in the current research are summarized.
Judicial control in administrative law has become a necessity in administrations. Given the significant role it plays in confronting illegal activities and preserving property, money and the security of individuals in society. This research aims to introduce judicial in the United Arab Emirates and discuss the relationship between cause and causation.The descriptive analytical approach was used to study the research problem.the research conclude that cause and causation the most important element that enables the judiciary control the legality of the administration’s decisions. It is of great importance safeguards to protect individuals from abuse of administration by informing the person concerned of the reasons for making the decision, since the administration, in exercising its powers, must respect the set of legal rules established for it in the State.the research recommend that the competent authorities to make causation an essential part of the cause and a failure to render administrative decisions null and void in order to ensure transparency and to affirm the rule of law, with the exception of acts of supreme sovereignty, in order to preserve the supreme interest of the State.
