The subject of materials science will serve to understand the basic principles of materials engineering to understand the relationship between the chemical structure and composition with their properties, to finally find their application in our society. These concepts are considered basic to be able to understand and design in the near future materials with biological applications and therefore, their application in bioengineering.

The objective of the subject is that the student acquires knowledge of the fundamentals of materials science, their structure and their defects, and how they relate to the final properties of the materials.
To know different techniques of microstructural characterization, as well as to know how to interpret the results obtained through the different techniques.
Knowledge of the fundamentals of science, technology and materials chemistry. Understand the relationship
between the microstructure, the synthesis or processing and the properties of the materials.
Solve problems related to the engineering of the manufacturing processes, based on the materials
that make up the element.
Acquire knowledge of the fundamentals of the families of the materials, their structure and defects.
To know different techniques of microstructural characterization, as well as to know how to interpret the results obtained through the different techniques.

6) Structure and characterization of polymers
- Obtaining the polymers (polymerization reactions). Molecular molecular mass and techniques for
determination.
- Molecular architecture (linear, branched and reticulated) and classification of polymers in thermoplastics,
thermostable and elastomers.
- Structure of polymers (amorphous and semi-crystalline). Techniques for the determination of the transition temperature
vitreous
- Copolymers.
Classes will be taught in theoretical format, problems and laboratory practices where competences will be introduced
specific to the subject. There will be face-to-face activities to work on oral and written communication and
teamwork.
The student's grade will be:
Final grade = 0.5 Final Exam + 0.3 Partial Exam + 0.2 Practical classes (exercises to solve / presentation / laboratory)
Second call
Final grade = 0.8 Second call exam + 0.2 Practical classes
