Ciência e Engenharia dos Materiais Fibrosos
This curricular unit aims to deepen the knowledge of the PhD student in fibrous materials, including natural polymers, in particular in the domains of the relationships between structure and properties, as well as their integration into fibrous structures with new functionalities for applications in innovative materials.
Knowledge, skills and competences:
To analyze the relationship between the structure of polymers and the morphology of nanoelements;
Describe the structure and properties of the main organic and inorganic natural polymers;
Analyze the influence of processing on the morphology and properties of polymeric materials;
To discuss the structure of the fibrous materials at different scales and to analyze the relations with the macroscopic properties;
To analyze the relationships between structure, morphology and macroscopic properties of fibrous materials;
To describe the behavioral basis of fibrous materials with special properties;
Select materials depending on the appli
