Different plants can be used to prepare nanoparticles. This is termed as green technology. It is one of the best ecofriendly and low-cost method for the preparation of nanoparticles which has no harmful effects. PbO nanoparticles were prepared by green method using leaf extract of Datura Sternum plants. The preparation of Lead oxide was confirmed by color change from colorless to yellowish brown. UV-Visible peak obtained at 250 nm and XRD study clarified the formation of PbO NPs. These PbO nanoparticles were then applied for the preparation of Nano Composite Polymer Membranes (nCPMs). PbO-PVC nCPMs were prepared based on polyvinyl chloride (PVC) polymer and PbO filler with the help of solution casting method, using cyclohexanone as a solvent. Different percentage (5-35%) of filler was used. The physiochemical parameters studied were viscosity, water uptake (WU), perpendicular swelling (DT) in deionized water, density, porosity (ε), morphology, ion adsorption capacity (IAC) and electrical conductivity (σ). The values of all these parameters except viscosity and conductivity were increased on increasing filler percentage. Viscosity of the nCPMs solution was decreased from 171 to 46.21. The conductivity of nCPMs was first increased upto 25% filler and then decreased. The deformation in PVC structure was increased on enhancing PbO amount. The values of Density, porosity, water uptake, DT and IAC were found in range 1.15-5.02, 0.50-0.87, 72.01-141.30, 0.012-0.11, and 3.13 × 107-8.60 × 107 respectively.

探索PbO-PVC纳米复合聚合物膜中绿色合成PbO纳米颗粒的理化评估。
可以使用不同的植物来制备纳米颗粒。这被称为绿色技术。它是制备无害纳米粒子的最佳环保，低成本方法之一。用曼陀罗植物的叶提取物通过绿色方法制备了PbO纳米颗粒。通过从无色到黄棕色的颜色变化证实了氧化铅的制备。在250 nm处获得的UV-可见峰和XRD研究澄清了PbO NP的形成。然后将这些PbO纳米颗粒用于制备纳米复合聚合物膜（nCPM）。在溶液浇铸法的帮助下，以环己酮为溶剂，基于聚氯乙烯（PVC）聚合物和PbO填料制备了PbO-PVC nCPM。使用了不同百分比（5-35％）的填料。研究的理化参数是粘度，去离子水的吸水率（WU），垂直溶胀（DT），密度，孔隙率（ε），形态，离子吸附能力（IAC）和电导率（σ）。所有这些参数（粘度和电导率除外）的值都随着填料百分比的增加而增加。nCPMs溶液的粘度从171降低至46.21。首先将nCPM的电导率提高到25％，然后降低。随着PbO含量的增加，PVC结构的形变增加。密度，孔隙率，吸水率，DT和IAC的值分别在1.15-5.02、0.50-0.87、72.01-141.30、0.012-0.11和3.13×107-8.60×107的范围内。所有这些参数（粘度和电导率除外）的值都随着填料百分比的增加而增加。nCPMs溶液的粘度从171降低至46.21。首先将nCPM的电导率提高到25％，然后降低。随着PbO含量的增加，PVC结构的形变增加。密度，孔隙率，吸水率，DT和IAC的值分别在1.15-5.02、0.50-0.87、72.01-141.30、0.012-0.11和3.13×107-8.60×107的范围内。所有这些参数（粘度和电导率除外）的值都随着填料百分比的增加而增加。nCPMs溶液的粘度从171降低至46.21。首先将nCPM的电导率提高到25％，然后降低。随着PbO含量的增加，PVC结构的形变增加。密度，孔隙率，吸水率，DT和IAC的值分别在1.15-5.02、0.50-0.87、72.01-141.30、0.012-0.11和3.13×107-8.60×107的范围内。
