In this study, PSG composite films were prepared by casting method by adding graphene (G) to glycerol plasticized potato starch (PS) films. The structure and properties of the composite films were investigated attenuated total reflectance Fourier transform infrared (ATR‐FTIR), X‐ray analysis (XRD), and swelling capacity, total soluble matter, transparency, tensile strength, and electrical conductivity. When the G content of PSG composite films increased from 0% to 1%, tensile strength increased from 1.035 MPa to 1.681 MPa, but decreased to 1.175 MPa in composite films containing 2% G. It also increased electrical conductivity when the G concentration increased. Also, the G layers are among the PS films and their swelling and solubility properties are reduced. With increased G concentration, the light transmittance decreased and the films were more opaque. These improvements can refer to the interface interaction between PS and G.

石墨烯增强的马铃薯淀粉复合膜：改善机械性能，阻隔性能和电性能

在这项研究中，通过在石墨化的马铃薯淀粉（PS）膜中添加石墨烯（G）的流延方法制备PSG复合膜。研究了复合膜的结构和性能，包括衰减全反射傅里叶变换红外光谱（ATR‐FTIR），X射线分析（XRD）以及溶胀能力，总可溶物，透明度，拉伸强度和电导率。当PSG复合膜的G含量从0％增加到1％时，拉伸强度从1.035 MPa增加到1.681 MPa，但在含2％G的复合膜中降低到1.175 MPa。当G浓度增加时，导电率也增加。而且，G层在PS膜中，并且它们的溶胀和溶解性降低。随着G浓度的增加，透光率降低，薄膜不透明。这些改进可以参考PS和G之间的接口交互。
