In this research, the functionalization of α-MnO nanorods (NRs) was conducted with stearic acid (SA) through solvothermal technique. The α-MnO-SA NRs were used as nanofiller for the preparation of blend nanocomposites (NCs) based on poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP) by ultrasonic irradiation. The results exhibit that with increasing in α-MnO-SA quantity, the thermal stability of blend NCs was improved. Morphological studies revealed that α-MnO-SA with rod structure and a diameter size of 25-80nm was uniformly dispersed in the PVA and PVP matrices. The use of ultrasonic was responsible for these great homogeneities which could not be achieved by mechanical or magnetically stirring. The prepared blend NCs were exploited as an adsorbing for uptake of Cd ion from the aqueous system. The results indicated that they can be potentially utilized for the elimination of Cd ion from an aqueous system with q of 47(mgg).
在本研究中，通过溶剂热技术用硬脂酸（SA）对α-MnO纳米棒（NRs）进行功能化处理。α-MnO-SA纳米棒用作纳米填料，通过超声辐射制备基于聚乙烯醇（PVA）和聚乙烯吡咯烷酮（PVP）的共混纳米复合材料（NCs）。结果表明，随着α-MnO-SA用量的增加，共混纳米复合材料的热稳定性得到提高。形态学研究表明，具有棒状结构且直径尺寸为25-80nm的α-MnO-SA均匀分散在PVA和PVP基质中。超声的使用导致了这些优异的均匀性，而通过机械搅拌或磁力搅拌无法实现。制备的共混纳米复合材料被用作从水体系中吸附镉离子的吸附剂。结果表明，它们有望用于从水体系中去除镉离子，q为47（mg/g）。
