Electrospun Bifunctional Janus Nanobelts

In 2014, electrospun bifunctional Janus nanobelts were fabricated by Dong and coworkers (Ma et al., 2014). The setup is shown in Fig. 5.16A. Nanobelts are characterized by anisotropy, large width/ thickness ratio, and unique optical, electrical, and magnetic properties that are different from those of nanofibers. The side-by-side nanofibers these authors made included Fe3O4/PMMA as one side, while the component of the other side was Tb(BA)3phen/PMMA. The SEM image of the nanobelts obtained by side-by-side electrospinning is shown in Fig. 5.16BeD shows the EDS line scan analysis of the nanobelts, which confirmed the morphology of side by side. Compared with the Fe3O4/Tb(BA)3phen/ PMMA composite nanobelts, the biphasic Janus nanobelts possessed both high fluorescence intensity and saturation magnetization.
