Characterization of Polymer Thermal Properties
EMSL Project ID
1762
Abstract
Polymer/metal multilayers are being widely used in optical, packaging, semiconductor, and display industries.Such multilayer stacks can be fabricated in-line and at high speed in a web-coater by combining the polymermultilayer technology and those of traditional metal/metal oxide depositions, such as evaporation (e-beam/thermal heating), sputtering, and CVD. One primary concern in these applications is the thermal stability of the polymer layers. It is well known that polymer properties evolve with temperatures. These properties exhibit sharp changes around the glass transition temperature (Tg) and may suffer significant losses due to thermal oxidation at temperatures (maximum service temperatures)well below the polymer melting point. We plan to use the Differential scanning caloriometry (DSC)and thermal ovens in Lab. 1421 to characterize the thermal properties of our polymer layers deposited in a web-coater. Polymer thin films (6x6) will be cut into small pieces and loaded into the DSC cell for the detection of glass transition and maximum service temperatures. The measurements will be performed in both air and N2 environments. Tests will also be performed using thermal ovens to evaluate the deformation of polymer samples at high temperatures.
