  • The objective of the project is the production and characterization of new composites having special properties, for inteligent materials using the newest knowledge and methods in the field of the synthesis of hybride materials and of polymer composites. The project starts from capacity of the macromolecular compounds to form mesophases if the rigidity is ensured, either by the interaction of lateral catenes or by the presence of mesogene groups of the type of azo or azomethine chromogenes. The specific macromolecular structure of the materials which are aimed to be obtained ensure advantages in what regards the anisothropy, thermal stability, versatility and manevrability.
  • The novelty is the synthesis in microwave field of some chromogen-polymer compounds with liquid crystal properties by linking an epoxy resins with variable molecular mass of some dyes with azo or azomethine structure. The composite materials have a molecular rigidity, of interest being those structures in which the rigid domains are dispersed at molecular level in polymer materials with flexible catenes leading to compounds having liquid crystal properties. Such compounds will be used in host-guest systems of the tridimensional epoxide type as well as in epoxi composites obtained from inorganic compounds of stratificate structure and hybrid polymers derivatives of alcoxysilanes functionalized with organic reactive groups.
  • The project can be part of the general objective of the program or development of partnerships of national R&D institutes, universities, academic institutes, for the development of new materials, products and processes with high added value which lead to technologies and “high-tech” products and prepare the mechanisms for implementing in the domains of optical storage of information, nonlinear optics, holographic applications, etc..
