通过熔融混合吹膜工艺（PBAT-HMNC）制备了由聚（己二酸-对苯二甲酸丁二醇酯）（PBAT）、热塑性淀粉、疏水改性纳米原纤化纤维素（HMNC）和绿色表面活性剂（蔗糖脂肪酸酯）组成的可生物降解复合材料。使用傅里叶变换红外光谱仪（FT-IR）、扫描电子显微镜（SEM）和热重分析仪（TGA）对复合材料进行了表征。系统地研究了机械性能和阻隔性能。结果表明，PBAT-HMNC复合材料表现出优异的机械性能和阻隔性能。当HMNC含量为0.6%时，拉伸强度达到最大值（超过13 MPa），热分解温度降低1~2℃。 0.6 wt% HMNC 通过薄膜弯曲工艺制备的复合材料的水蒸气透过率 (WVTR) 和氧气透过率 (OTR) 最低，分别为 389 g/(m2·day) 和 782 cc/(m2·day)，分别降低了 51.3% 和 42.1%。使用0.6wt%HMNC的薄膜保存11天后，姬松茸仍具有商品价值。 PBAT-HMNC复合材料已被证明是有前途的包装用纳米复合材料。
Biodegradable composites consisting of Poly-(butylene adipate-co-terephthalate) (PBAT), thermoplastic starch, hydrophobically modified nanofibrillated cellulose (HMNC), and green surfactant (sucrose fatty acid ester) were prepared via the melt-mixing and film-blowing process (PBAT-HMNC). The composites were characterized using the Fourier transform infrared spectroscope (FT-IR), scanning electron microscope (SEM), and thermogravimetric analyzer (TGA). The mechanical and barrier properties were systematically studied. The results indicated that PBAT-HMNC composites exhibited excellent mechanical and barrier properties. The tensile strength reached the maximum value (over 13 MPa) when the HMNC content was 0.6% and the thermal decomposition temperature decreased by 1 to 2 °C. The lowest values of the water vapor transmission rate (WVTR) and the oxygen transmission rate (OTR) were obtained from the composite with 0.6 wt% HMNC, prepared via the film-bowing process with the values of 389 g/(m2·day) and 782 cc/(m2·day), which decreased by 51.3% and 42.1%, respectively. The Agaricus mushrooms still had a commodity value after 11 days of preservation using the film with 0.6 wt% HMNC. PBAT-HMNC composites have been proven to be promising nanocomposite materials for packaging.
