The preparation of composites of synthetic and natural polymers represent an interesting option to combine properties; in this manner, polypropylene and chitosan extruded films using a different proportion of components and polypropylene-graft-maleic anhydride (PPgMA) as compatibilizer were prepared. The effect of the content of the biopolymer in the polypropylene (PP) matrix, the addition of compatibilizer, and the particle size on the properties of the composites was analyzed using characterization by fourier transform-infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), tensile strength, and contact angle, finding that in general, the addition of the compatibilizer and reducing the particle size of the chitosan, favored the physicochemical and morphological properties of the films.
合成聚合物与天然聚合物复合材料的制备是一种将多种性能结合起来的有趣选择；通过这种方式，制备了使用不同组分比例的聚丙烯和壳聚糖挤出薄膜，并以聚丙烯接枝马来酸酐（PPgMA）作为增容剂。采用傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、差示扫描量热法（DSC）、拉伸强度和接触角等表征手段，分析了生物聚合物在聚丙烯（PP）基体中的含量、增容剂的添加以及粒径对复合材料性能的影响，发现一般而言，增容剂的添加和壳聚糖粒径的减小有利于薄膜的物理化学和形态性能。
