Dynamic Mechanical Analysis In Polymers For Medical Applications
Published 2002 · Materials Science
The Dynamic Mechanical Analysis (DMA) is a powerful thermal analysis technique, which allows to detect phase transitions and relaxation processes in a variety of materials. With this technique, the solid-state rheological properties of viscoelastic materials can be characterised over a wide range of temperature and frequencies. This chapter summarizes the principles and the capabilities of the DMA technique focusing on its uses on polymeric-based systems aimed to medical and environmental applications. The examples presented include the materials that have been investigated in our research group in the last few years, such as starch-based blends, proteins, polyethylenes, and composites thereof, among other materials. These newly developed biomaterials are being proposed for a range of biomedicai applications that go from fracture replacement/fixation and tissue engineering scaffolding, to new partially degradable bone cements and hydrogels, carriers for controlled release of drugs and growth factors and new wound dressings and membranes.
