Biopolymers as films are defined as materials prepared from biological molecules with filmogenic morphology that can be versatile uses. The present research aimed to study formulations of natural polymeric composites based on babassu coconut mesocarp (BCM), alginate and glycerol, to verify the effect of these components on moisture, solubility, thickness and water vapor permeability (WVP) parameters for different cross-linking stages. After a second cross-linking was applied, they presented lower thickness, solubility, and WVP values than first cross-linking. Consecutive analyses for selected film formulations showed that the formulation to solutions of 400 mL with 3g of BCM, 7.5g of alginate and 4.0g of glycerol had the most promising results when correlating physical parameters with thermal analyses, chemical and mechanical properties. Films with amount of babassu coconut mesocarp in the proportion established were sturdy to solubility, leaching and thermal degradation, improved by second cross-linking applied.

藻酸盐和巴巴苏椰子中果皮的生物聚合物薄膜的制备和表征。

作为膜的生物聚合物被定义为由具有成膜形态的生物分子制备的材料，可以广泛使用。本研究旨在研究基于巴巴苏椰子中果皮（BCM），藻酸盐和甘油的天然聚合物复合材料的配方，以验证这些组分对水分，溶解度，厚度和水蒸气透过率（WVP）参数对于不同交联的影响。阶段。进行第二次交联后，它们的厚度，溶解度和WVP值均低于第一次交联。对选定的薄膜配方进行的连续分析表明，将物理参数与热分析，化学和机械性能相关联时，以3mL的BCM，7.5g的藻酸盐和4.0g的甘油溶液配制的溶液具有最有希望的结果。
