SC01) Polymer Nanocomposites and their Characterization via NMR
By Prof. Dr. Maria Ines Bruno Tavares

Full Professor, IMA, Federal University of Rio de Janeiro, RJ, Brazil
ABSTRACT: The obtaining of polymer nanocomposites developed very quickly because of the polymer diversity of applications, which is a great advantage to produce innovative materials. Since we can obtain polymer nanocomposites from many ways their morphology is an essential part of the new materials and to better understand the behavior of these new materials we have to characterize them.  Therefore, these materials must be investigated by many techniques. NMR is a spectroscopy that permits us to evaluate the morphology of the nanoparticle dispersed in the polymer matrix, due to the intermolecular forces which will infer in the nanoparticles dispersion and distribution in the polymer matrix. NMR has also several techniques that will give us many information. As polymer nanocomposites are heterogeneous materials to know how the dispersion and distribution of the nanoparticle is will give response on sample behavior. One of the best solid state NMR techniques is relaxometry, through the determination of proton spin-lattice relaxation time.

SC02) Composite Processing by Vacuum Infusion (Practical Course) 
By Eng. José Carlos Santiago

Marine Composites, RJ, Brazil
PROGRAM: Basic presentation about the utilized materials and the process of vacuum infusion. Gel time test (catalysis of 3 samples of 200g of resin with 1.5%, 2.0% and 2.5% to assess time and gel temperature). Infusion demonstration (small infusion assembled by the instructors to demonstrate the process and give tips about the set up). Division of participants in 4 groups and set up of 4 small infusions (with aid of the instructors). Closing and questions section.
