本文介绍了一种新型的纤维素/聚（3-羟基丁酸酯）共混物基电活性聚合物。研究了其制作工艺、弯曲驱动试验及其特性。为了制备这种新的EAP，将纤维素和PHB溶解在三氟乙酸中。将溶液浇铸以形成膜，随后在膜的两侧上沉积薄金电极。采用傅里叶变换红外光谱、扫描电镜、X射线衍射、差示扫描量热仪、拉伸试验和动态力学分析等手段对纤维素/聚羟基丁酸（PHB）复合膜的性能进行了研究。通过自由弯曲位移、电能消耗输出和环境条件下的寿命测试来评估弯曲性能。初步结果表明，这种纤维素/聚羟基丁酸酯共混物EAP对湿度的敏感性较低，在室温湿度条件下比纯纤维素EAP具有更高的弯曲位移和更长的使用寿命。这些结果表明，这种新的纤维素/聚羟基丁酸酯共混物EAP具有许多仿生应用的潜力。
This paper describes a novel cellulose/poly(3-hydroxybutyrate) blend based electroactive polymer. The fabrication process, bending actuation test and its characteristics are investigated. To prepare this new EAP, cellulose and PHB were dissolved in trifluoroacetic acid. The solution was cast to form a film followed by depositing thin gold electrode on both sides of the film. The characteristics of the cellulose/PHB film were investigated by Fourier transform infrared spectra, scanning electron microscopy, X-ray diffraction differential scanning calorimetry, tensile test and dynamic mechanical analysis. The bending performance was evaluated in terms of free bending displacement, electrical power consumption output and lifetime test under ambient conditions. Primary results show that this cellulose/PHB blend EAP is less sensitive to humidity and it shows higher bending displacement and longer lifetime than pure cellulose EAP at room humidity condition. These results indicate that this new cellulose/PHB blend EAP has potential for many biomimetic applications.
