摘　　要：采用差示扫描量热仪(DSC)方法研究尼龙6(PA6)及尼龙6/聚烯烃弹性体(POE)/黏土纳米复合材料的非等温结晶及熔融行为,随着降温速率的增加,PA6和PA6/POE/黏土纳米复合材料的结晶峰变宽,结晶峰向低温移动。在相同降温速率下,PA6/POE/黏土纳米复合材料在更高的温度下结晶;PA6和PA6/POE/黏土纳米复合材料中晶体呈三维生长,降温速率的增加和有机黏土的加入会使体系结晶速率增加;PA6/POE/黏土纳米复合材料的结晶活化能低于PA6。Nonisothermal crystallization and melting behavior of nylon 6 （ PA6 ） and nylon 6/ployolefin elastomer（POE） / clay nanocomposite by differential scanning calorimetry （DSC） were mainly investigated. Nonisothermal crystallization curves showed that crystallization exotherms baeame wider and crystallization peak temperatures shifted to a lower temperature with the increasing of cooling rate. Under the same cooling rate, crystallization peak temperature of PA6/POE/elay nanoeomposite was higher than that of PA6. Crystals in PA6 and nanocomposite grew with three-dimensional direction. Increasing cooling rate and organoclay could accelerate the crystallization. The crystallization activation energy of PA6/POE/clay nanocomposite was smaller than that of pure PA6.
