摘要

采用低温水热法在超高分子量聚乙烯(UHMWPE)纤维表面成功制备了致密均匀的ZnO纳米棒阵列，利用纳米棒阵列与树脂形成啮合结构，有效增强了纤维和树脂之间的界面结合强度. 采用扫描电镜(SEM)、示差扫描量热法(DSC)、热重分析(TGA)、X射线衍射(XRD)等手段对纤维改性前后结构与性能变化进行了分析，并通过单丝拔出实验表征了其与环氧树脂间的界面剪切强度(IFSS)；探索了反应时间、前驱液浓度对界面性能的影响. 研究结果表明这种改性方法对纤维的本征性能几乎无影响，改性后纤维增重仅5%，而与树脂复合后界面剪切强度提升58%，单丝拨出时破坏发生在纳米棒阵列与纤维之间. 进一步，利用该方法对UHMWPE织物进行改性，发现使用单宁酸可提高纳米棒阵列与纤维之间的结合力，使得到的UHMWPE@ZnO和UHMWPE@TA-ZnO织物的防穿刺能力分别提升20%和42%.

Abstract

Dense and uniform arrays of ZnO nanorods were successfully formed on the surface of ultra high molecular weight polyethylene (UHMWPE) fiber

via

low temperature hydrothermal method. The resultant microstructure could effectively enhance the interfacial bonding strength between the fiber and the resin due to its ability to form a mechanical meshing structure with the resin. Scanning electron microscopy (SEM)

differential scanning calorimetry (DSC)

thermogravimetric analysis (TGA)

X-ray diffraction (XRD) were used to analyze the structure and properties of UHMWPE fibers before and after modification

and the monofilament pull-out experiment was performed to characterize the interfacial shear strength (IFSS) between the fiber and epoxy resin

exploring the effects of reaction time and precursor concentration on interface properties. The results showed that this gentle modification process had little effect on the intrinsic properties of the fiber

and the IFSS could be 58% higher than that of the unmodified fiber. In addition

the UHMWPE fabric was modified by the similar method

and the puncture work was improved by 20% for the UHMWPE@ZnO fabric. The puncture work was further improved by 42% when tannic acid was introduced at the interface to enhance the binding force between ZnO nanorods and fiber surface.
