摘要
以聚乙烯醇(PVA)和醋酸锌[Zn(Ac)2]为前驱物,通过静电纺丝法制备合成纤维网络状氧化锌。利用X射线粉末衍射、扫描电镜、矢量网络分析仪对其结构、形貌和微波吸收性能进行表征。结果表明:利用静电纺丝法可获得直径约为300nm、长径比可达600∶1的纤维网络状氧化锌;与棒状结构相比其具有更强的电磁波吸收能力,与石蜡混合物(质量比3∶1)微波衰减最大值达-28dB,吸波频段较宽。
Zinc oxide fibers were fabricated through electrospinning a precursor of PVA and Zn(Ac)2. The morphology and structure of the product were characterized by XRD and SEM. Its electromagnetic wave absorption property was characterized by network analyzer. It turned out that: Zinc oxide fibers, a diameter of 300 nm and draw ratio of 600 ∶ 1, were obtained through electrospinning; compared with Zn O rob, the samples have good electromagnetic wave absorption ability and wide frequency range; the microwave attenuation achieve maximum come to-28 d B.
