Water absorption and hydrothermal ageing effects on tensile properties of nanofibrillated cellulose/biobased poly(butylene succinate) composites

The dataset provides experimental data on water absorption and tensile properties of bio-based poly(butylene succinate) (PBS) composites containing nanofibrillated cellulose (NFC) of 5, 10, 20, 30, and 50 wt.% (5NFC, 10NFC, 20NFC, 30NFC, 50NFC, respectively). PBS/NFC composite films (thickness 0.2 mm) were produced by solution casting. The effect of humid environment (RH = 98%, T = 22 °C; denoted as RH98) and hot distilled water (T = 50 °C; denoted as W50) on tensile properties was studied. Data can be useful for modelling water absorption of biopolymer/NFC based composites and assessment of the NFC reinforcement efficiency under the environmental impact.

本数据集包含添加质量分数分别为5%、10%、20%、30%与50%纳米纤丝纤维素（nanofibrillated cellulose, NFC）的生物基聚丁二酸丁二醇酯（poly(butylene succinate), PBS）复合材料的吸水性与拉伸性能实验数据，各组试样分别记为5NFC、10NFC、20NFC、30NFC与50NFC。采用溶液流延法制备了厚度为0.2 mm的PBS/NFC复合薄膜，探究了湿热环境（相对湿度RH=98%，温度T=22℃，记为RH98）与热蒸馏水（温度T=50℃，记为W50）对该复合材料拉伸性能的影响。本数据集可用于生物聚合物/NFC基复合材料的吸水行为建模，以及环境影响下NFC增强效率的评估。
