Polymer nanocomposites of Poly (styrene co-acrylonitrile)/Nickel Oxide (PSAN/NiO) have been prepared. The increased free volume sizes up to 0.4 wt% of NiO loading indicates overall reduction in packing density of polymer network. The decreased o-Ps lifetime (τ₃) at higher concentration of NiO indicates improved interfacial interaction between the surface of NiO nanoparticles and side chain of PSAN polymer matrix. The increased AC/DC conductivity at lower wt% of NiO loading demonstrates increased number of electric charge carriers/ mobile ions and their mobility. The increased dielectric constant and dielectric loss up to 0.4 wt% of NiO loading suggests the increased dipoles polarization.

已经制备了聚（苯乙烯共丙烯腈）/氧化镍（PSAN / NiO）的聚合物纳米复合材料。高达NiO负载的0.4 wt％的增加的自由体积大小表明聚合物网络的堆积密度总体降低。减小的o-Ps寿命（τ ₃在氧化镍的浓度更高）表明改进的NiO纳米颗粒的表面和PSAN聚合物基质的侧链之间的界面相互作用。在较低的NiO含量（wt％）下增加的AC / DC电导率表明，电荷载流子/移动离子的数量及其迁移率增加。介电常数的增加和高达NiO负载的0.4 wt％的介电损耗表明偶极子极化增加。
