Abstract

Nano-Iaminate coatings with highly ordered and oriented nanostructures based on Organically Modified Montmorillonite (o-MMT) were formed via co-assembling with polymer binders and applied by using various coating methods including spray coating, dip coating and blade cast coating for making films/coatings with enhanced dielectric and electrical discharge resistance. Dielectric properties of the nanoclay coatings along with their nanostructure characterization were studied for the coating processing optimization. The DC breakdown strength test and small-angle x-ray diffraction results consistently indicated that dip coated samples led to the most highly oriented nano-Iaminated structure with the highest breakdown strength. Corona endurance test was also performed on dip coated MMT nano-composite materials in comparison with other commercial available discharge resistant film. A remarkable enhancement was observed for nano-Iaminate coating, which indicated that this new nano-composite material has potential to be a processable and cost-effective dielectric material for many applications where discharge resistance device/structure/materials are needed.

耐放电纳米涂层

以有机改性蒙脱土(o-MMT)为基材，通过与高分子粘合剂共组装形成具有高度有序取向纳米结构的纳米亚胺酸盐涂层，并采用喷涂、浸渍和叶片铸造等多种涂层方法制备具有增强介电和放电电阻的薄膜/涂层。研究了纳米粘土涂层的介电性能及其纳米结构表征，以优化涂层工艺。直流击穿强度测试和小角度x射线衍射结果一致表明，浸镀样品具有最高击穿强度和最高取向的纳米复合结构。对浸涂MMT纳米复合材料进行了电晕耐久性试验，并与其他市售的抗放电膜进行了比较。纳米亚胺酸盐涂层有显著的增强，这表明这种新型纳米复合材料有潜力成为一种可加工且具有成本效益的介电材料，适用于许多需要放电电阻器件/结构/材料的应用。
