Project Objectives The aim of this project is to obtain elastomeric films from blends of Natural Rubber (NR) from Hevea Brasiliensis trees (Seringueira) and a derivative of polyaniline, poly(o-methoxyaniline)(POMA) doped with camphor sulphonic acid (CSA), by casting. The films will be studied by conductivity measurements, infra red spectroscopy (FTIR), UV-Vis-NIR spectroscopy, scanning electron microscopy (SEM), and Thermogravimetric analysis (TGA).
Required skills

It is necessary that student has some Knowledge about science of polymer.
The student will collect the latex from mangabeira tree and through physical and chemical process he will obtain a “pure” rubber. The natural rubber will be dissolved using an appropriate solvent and mixed with a conductivity polymer (POMA) in different composition. The films will be obtained by casting theses blends on a suitable substract.
Techniques to be used

Conductivity measurements, infra red spectroscopy (FTIR), UV-Vis-NIR spectroscopy, scanning electron microscopy (SEM), and Thermogravimetric analysis (TGA).
If necessary, the student will be asked to perform analyses in laboratories of other universities that we have collaboration in a short time basis.
Schedule of Activities In the first, second e third month the student will learn basic concept about polymer, especially conducting polymer and natural rubber. The student also will learn how to prepare a pure rubber and to make the POMA synthesis. In the fourth and fifth month the student will prepare the films and characterize them. The report will be done at the end of sixth month.
