The Chemical Synthesis and Thermoanalysis Laboratory is a space dedicated to the study and development of materials through chemical synthesis and thermoanalytical analysis. This laboratory has several key instruments, including a DSC (Differential Scanning Calorimeter), a TGA (Thermogravimetric Analysis), a rheometer and a DMA (Dynamic-Mechanical Analysis).
The DSC is used to investigate changes in the heat absorbed or released by a sample during thermal processes. It allows the study of phase transitions, thermal stability, chemical reactions and other heat-related phenomena. DSC records the temperature difference between the sample and a reference while undergoing a controlled heating or cooling programme.
TGA measures changes in the mass of a sample as a function of temperature or time. This thermogravimetric analysis makes it possible to determine the composition of the sample, identify the presence of different components, evaluate thermal stability, and analyse decomposition or mass loss during heating processes.
The rheometer measures rheological properties of materials, i.e. how they flow and respond to the application of forces. It allows the study of viscosity, elastic and viscoelastic behaviour, flow and deformation of liquid and solid materials. The rheometer is used in the characterisation of polymers, fluids and complex materials.
DMA allows the mechanical and dynamic properties of materials to be analysed. It measures the modulus of elasticity, flow resistance, stiffness and damping capacity of a sample under different temperature and frequency conditions. DMA is widely used in the study of polymers, composites and biomaterials.
These instruments in the Chemical Synthesis and Thermoanalysis Laboratory are essential for the design, study and development of new materials. Chemical synthesis allows the fabrication of tailor-made materials, while thermoanalytical analysis provides crucial information on thermal stability, purity, phase transitions and other fundamental aspects of materials. The use of rheometer and DMA allows understanding and control of the mechanical and rheological properties of materials, which is essential for their application in various industries, such as automotive, electronics, medicine and many others.
