用正电子湮没寿命谱(PALS)研究了天然橡胶/炭黑复合材料硫化过程中自由体积随时间变化的行为。测量了正电子正电子(o-Ps)拾取湮没寿命和强度分别与平均尺寸和孔洞数随固化时间的变化关系。样品在160℃固化，而所有的PALS测量都是在室温下进行的。还报道了D706(杜拉烯-706)合成橡胶的硫化结果，并与天然橡胶(NR)的硫化结果进行了比较。(2007 Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
The free volume behavior as a function of time during curing of natural rubber-carbon black composites studied by positron annihilation lifetime spectroscopy (PALS) is reported. The lifetime and intensity of the ortho-positronium (o-Ps) pick-off annihilation, which correlate with the average size and the number of holes respectively, were measured as a function of curing time. The samples were cured at 160 °C, while all PALS measurements were made at room temperature. Results for curing D706 (Duradene-706), a synthetic rubber is also reported and compared with those found from natural rubber (NR). (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
