SEM characteristics of GRS-PVA electrospun fibers are illustrated in Fig.2 and fiber diameter sizes of each formulation were reported in Table 2.The smooth fibers were obtained at PVA concentration from 8%to 10%（w/v）.At 5%PVA（w/v），it was not possible to obtain smooth fibers，as seen in Fig.2A-C.They are beaded fibers in which similar to the findings from Supaphol and Chuangchote[20].The GRS-PVA nanofibers that contain 8%PVA（w/v）with 1–3%GRS（w/v）formed smooth fibers with an average diameter of 191–263 nm as shown in Fig.2D-F.The copolymer nanofibers of 10%PVA（w/v）with 1and 2%GRS（w/v）also formed smooth fibers，but they demonstrated a larger fibrous diameter than the copolymer nanofibers of 8%PVA（w/v）with 1–3%GRS（w/v）.On the other hand，increasing GRS to 3%（w/v）with 10%（w/v）PVA was not possible to fabricate the nanofibers because the solution possessed a high viscosity.Consequently，it led to a clogging at the tip of the needle which impedes electrospinning process.Starch has been reported as detrimental to an electro spinnability of polymer blends[28].
