Different contents of silicon carbide (SiC) nanowires were mixed with Poly(vinylidene fluoride) (PVDF) to facilitate the polar phase crystallization. It was shown that the annealing temperature and SiC content affected on the phase and crystalline structures of PVDF/SiC samples. Furthermore, the addition of SiC nanowire enhanced the transformation of non -polar a phase to polar phases and increased the relative fraction of 13 phase in PVDF. Due to the nucleating agent mechanism of SiC nanowires, the ion dipole interaction between the negatively charged surface of SiC nanowires and the positive CH2 groups in PVDF facilitated the formation of polar phases in PVDF.

Owing to the superiority of being flexible, highly conductive, and extremely transparent, silver nanowire (AgNW) has been regarded as a possible candidate to replace indium-tin-oxide (ITO) for flexible transparent conductive films (TCFs), flexible electronics, and flexible display applications. To make TCFs with lower sheet resistance (R-s), but without sacrificing the optical transmittance, the deployment of AgNWs is very critical. A crossed-alignment method along with multi-stacking structure was proposed to lower the percolative threshold, which thus can decrease the R-s by a factor of more than two, in the premise of not affecting the optical transmittance.
