采用微量热技术表征Tg特性
|
| The detection of the glass transition (Tg) is a fundamental and important measurement in the thermal analysis of polymers. Thermomechanical analysis (TMA) is a basic technique that easily measures the Tg in many polymers. In TMA, a probe is placed on a sample surface and detects Tg by either expansion or penetration as the sample is heated. Recently, the advent of a new thermal analysis technique, Micro Thermal Analysis (μTATM), has introduced a thermomechanical technique based on detecting expansion or penetration with a thermal Atomic Force Microscopy (AFM) probe. This technique, termed μTMATM, can also detect Tg by penetration, but on cubic micrometer size volumes of material. As opposed to “macro” TMA, μTMA functions by heating the thermal probe. Characteristics of how this new technique detects Tg will be discussed. |
