Melt Electrospinning: A Green Method to Produce Superfine Fi_刘勇、李凯丽、（印度）阿泽、（新加坡）席瑞思著_9787122397997

熔体静电纺丝是纳米纤维制造的新兴技术之一，其的特点是不用添加溶剂，具有无毒、环保、安全、经济等方面的优势。在生物医学、药物控释、组织工程等方向具有广阔的应用前景。

本书基于作者多年的原创科研成果，对熔体静电纺丝技术做了全面的总结，共四部分。部分介绍了熔体静电纺丝的发明，包括离心熔体静电纺丝和向上熔体静电纺丝的独立发展，分别对两种方法的产率和纤维直径进行了优化。第二部分介绍了熔体的静电纺丝以及利用不同聚合物和自行设计的装置测试纤维性能的方法。第三部分介绍耗散粒子动力学模拟，这种模拟技术是模拟纺丝过程中分子链结构和取向的一种方法。第四部分介绍了离心熔体静电纺丝的原理、方法及改进措施。

本书不仅适合静电纺丝研究的广大科研人员阅读，同时还可供燃料电池、锂电池、太阳能电池、水过滤、空气过滤、血液过滤、组织工程、载药缓释、癌症检测、介入治疗支架、人造血管、金属吸附等可能用到纳米纤维的广大领域的科技工作者﹑研究生、企业管理人员参考。
