Abstract


We have synthesized in this work a new tetrafunctional epoxy prepolymer in two steps for the formulation of a new hybrid microcomposite with NTC as a load.

In a first step we synthesized the TBDGEBA based on tetrabromo of Bisphenol A for this purpose. In a second step, we proceeded to the chemical modification of this bifunctional pre-polymer precursor of TGEDADPTBBA by aniline as nucleophilic reagent which led to the synthesis of a tetrafunctional epoxy polymer TGEDADPTBBA. This epoxy prepolymer was then thermally crosslinked with methylene dianiline (MDA) in the presence of CNT based load in order to obtain new nano-composite materials at different percentages. The thermal study of these composite composites was studied by thermogravimetric analysis while the rheological characterization of the nanocomposites was carried out through the use of a RHM01-RD HAAKE rheometer.
