Abstract:
The starch/polyvinyl alcohol/graphene oxide composite film was prepared by casting method by adding GO to starch/PVA matrix. The effects of GO with different concentrations on the performance of the composite film were studied. With the increase of GO concentration, the thickness increased, the tensile strength increased first and then decreased. When the concentration of GO reached 2 mg/ml, the tensile strength was 25.28 MPa reaching the maximum. The increase of GO concentration caused the enhancement of film's moisture resistance. Through FTIR, SEM and TGA analysis, it was found that the addition of GO did not change the composition of the film, but it could change the phenomenon of matrix agglomeration and improve the thermal stability of the film. The preparation of composite films by adding GO could improve the properties, expand the application of nanomaterials in the food packaging field, and expand the research of biodegradable composite films.

In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.

02:19Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
