| description | The invention discloses a preparation method of a high-toughness biodegradable starch-based film, and belongs to the technical field of preparation of starch-based films. Ball-milled starch and PVA (polyvinyl alcohol) are used as main materials of the starch film, and sodium carboxymethyl cellulose is dissolved by a deep eutectic solvent to serve as a reinforcing material and a plasticizer of the film; and heating the mixed material at 50-90 DEG C, mechanically stirring to promote the uniform mixing of the material, and coating on a polyfluortetraethylene plate to obtain the biodegradable starch-based film. The biodegradable starch-based film prepared by the invention has the advantages of high toughness, good tensile strength, good hydrophobic property and the like.
本发明公开了一种高韧性可生物降解淀粉基薄膜的制备方法，属于淀粉基薄膜的制备技术领域，本发明利用球磨淀粉和PVA作为淀粉薄膜的主要材料，利用深共熔溶剂溶解羧甲基纤维素钠作为薄膜的增强材料和增塑剂，于50~90℃条件下对混合物料进行加热并机械搅拌促进物料混合均匀，再涂覆在聚四氟乙烯板上制得可生物降解淀粉基薄膜。本发明制备的可生物降解淀粉基薄膜具备高韧性、良好拉伸强度和疏水性能等优势。 |
