摘要
介绍了一种新的简单实用的制备大块聚合物/无机纳米复合材料的方法,即探索性地采用选择性激光烧结(SLS)法来制备聚合物/Al2O3纳米复合材料。结果表明,以表面已预处理的聚合物与纳米粒子Al2O3混合粉料作为SLS用粉,在一定的激光烧结工艺参数条件下,可将其烧结成纳米粒子均匀分散在聚合物基体中的块体材料;并可通过控制激光功率和扫描速度等激光烧结工艺参数获得不同性能的聚合物/纳米复合材料。
A new practical method for preparation of bulk polymer/Al_2O_3 nano-composites by selective laser sintering(SLS) was introduced. The results show that under the proper processing parameter conditions, surface pretreatment polymer and nano-Al_2O_3 mixture powders can be produced into bulk polymer/Al_2O_3 nano-composites, which nano-sized Al_2O_3 particles are uniformly located within polymer matrix, and different properties of polymer/nano-composite can be obtained by controlling laser power , scanning speed and other factors.
