塑料，玻璃，陶瓷的导热性分析及增强型导热塑料
摘要：
This study describes a new method for the measurement of thermal conductivity of insulating materials in the range
from 0.1 to 1.5 W/°C m which generally covers polymers, ceramics and glasses. The method is based on Modulated
DSC and includes no modification or additions to the apparatus itself. One additional calibration step is required to
compensate for heat loss through the inert purge gas surrounding the test specimen. Best case precision is on the
order of 2% with mean values compared to literature values within 1%. While work to date includes only temperatures
near ambient, measurements above and below ambient seem possible. Further work is also currently in progress to
evaluate the applicability of this method to a broader range of materials.
