Abstract

Recently, carbon nanotubes (CNT), specially the functionalized ones, have been added to polymeric matrix due to its excellent mechanical, electrical and thermal properties. The adding of CNTs into PEAD matrix, as reinforcement, can improve the matrix properties, but also changes the fusion/crystallization process. The fusion/crystallization process study is very important due to it affects the final properties of the composite. Moreover, several process variables can change the real role of CNTs as reinforcement in the PEAD matrix. Therefore, the goal of this project is to study the influence of three process variables in the crystallization an in the viscoelastic properties of CNT/PEAD composites: CNT amount, functionalization and alcane size. The samples will be prepared by mechanic mixing of fused polymer and casting by pressure. The viscoelastic properties and the composite homogeneity will be studied. The correlation between this information will give us to improve the understanding the interaction between CNT/PEAD, and to clear how the process variables can modify the composites crystallization process.
