In this paper, the authors modified polyacrilonitrile (PAN)/polyvinylfloride (PVDF) blends by loading the graphene (0.5 to 1.5 wt %).Abstract:
Polyacrilonitrile (PAN)/ Polyvinylfloride (PVDF) blends were modified by loading the graphene (0.5 to 1.5 wt %). The presence of graphene reveals the interesting surface properties. The decrease in surface roughness as function of graphene loading was confirmed by the topographic method of recording (two and three dimensional images) with atomic force microscope (AFM). The blends become smoother in nature due to occupied smaller surface area of graphene. This property may be useful for several applications in the marine, naval, nuclear domain and engineering applications as barrier medium.read more

TL;DR: It can be confirmed by looking at the statistical results of the filler-to-filler distance obtained from the digital processing of the fracture surface images that the various oxygenated functional groups of graphene oxide can help improve the dispersion of the filling and that the introduction of large phenyl groups to the graphene basal plane has a positive effect on the disp immersion.

Surface characteristics and hemocompatibility of PAN/PVDF blend membranes
TL;DR: In this article, polyacrylonitrile (PAN) was blended with polyvinylidine fluoride (PVDF) at various ratios and made into membranes, and the hemocompatibility of the resulting membranes was evaluated based on human plasma proteins adsorption, platelet adhesion, thrombus formation, and blood coagulation time.
