Název v původním jazyce

Comparison of thermal properties of neat a-PMMA and a-PMMA filled with CB

Popis výsledku v původním jazyce

In this work the effect of filler on thermal properties of amorphous matrix has been investigated. Atactic-poly(methyl methacrylate), a-PMMA, was used as polymer matrix and carbon black, CB, as nanofiller. Mercury-in-glass dilatometry and differential scanning calorimetry methods were used in experiment for comparison of thermal properties. The first measurements were performed to measure decrease in heat capacity and thermal expansion coefficient with amount of filler. From the difference between heatcapacity in liquid and glassy state quantity of immobilized a-PMMA has been calculated. Also reduction of activation energy of transition from liquid to glassy state has been measured. In general, the addition of filler changes the thermal properties ofamorphous a-PMMA. These properties consequently affect also behaviour of polymers in glassy region.
