In the study by Xiang Chen, Haibing Xu and Yingdan Zhu, a layer of poly(cyclotriphosphazene‐co‐4,4′‐sulfonyldiphonel) (PZS) hybrid coating with PZS microspheres were successfully introduced onto carbon fiber (CF) surface through facile in situ polymerization, which effectively improved the interfacial shear strength of CF reinforced polyamide 6 (PA6) composites. The mechanical interlocking and hydrogen bonding synergistically played a major role in the improvement of interfacial properties of composites. This figure shows a SEM micrograph of CF/PA6 microdroplet specimen for microbond test, providing an effective method to strengthen the interfacial properties of CF reinforced thermoplastic composites.

在陈翔，徐海兵和朱应丹的研究中，通过将PZS微球成功地引入到碳纤维（CF）表面，成功地将一层带有PZS微球的聚（环三磷腈-co-4,4'-磺酰基二电话）（PZS）杂化涂层层引入了碳纤维（CF）表面。原位聚合，可有效提高CF增强聚酰胺6（PA6）复合材料的界面剪切强度。机械联锁和氢键协同作用在改善复合材料的界面性能方面起着重要作用。该图显示了用于微粘结测试的CF / PA6微滴样品的SEM显微照片，为增强CF增强热塑性复合材料的界面性能提供了有效的方法。DOI：10.1002 / app.49577
