最近开发了一种简单而有效的喷涂方法来制备薄、柔性和透明的环氧薄膜，该薄膜以近晶液晶顺序剥离和高度取向的α-磷酸锆纳米片层增强。在这里，我们研究了同样的喷涂工艺制备的ZrP/环氧树脂纳米复合材料的耐划伤性能。并与纯环氧涂层进行了比较，确定了纳米氧化锆对涂层的影响。根据ASTMD7027/ISO 19252划痕标准进行了试验，并用不同的实验工具研究了划痕机理。结果表明，在环氧涂层中引入纳米ZrP膜后，涂层的耐刮擦性能有了较大的提高。这反映在微裂纹和犁削损伤的延迟以及摩擦划痕系数的降低上。这一结果归因于剥离和取向的ZrP纳米薄膜在提高环氧基复合材料的力学性能方面的重要作用。讨论了当前研究在开发高性能应用的新涂层系统方面的有用性。
A facile but efficient spray-coating method was recently developed to manufacture thin, flexible, and transparent epoxy films reinforced with well-exfoliated and highly-aligned α-zirconium phosphate (ZrP) nanoplatelets in smectic liquid crystalline order. Here, we investigate the scratch resistance of ZrP/epoxy nanocomposites prepared following the same spray-coating process. Comparison was made with neat epoxy coating to determine the impact of ZrP nanofillers. Tests were conducted with accordance to ASTM D7027/ISO 19252 scratch standard and scratch mechanisms were studied using different experimental tools. Results show that scratch resistance is considerably improved after introducing ZrP nanofillers to the epoxy coating. This was reflected by the delay in microcracking and plowing damages and the decrease of scratch coefficient of friction. This result is attributed to the significant role of exfoliated and aligned ZrP nanofillers in enhancing the mechanical properties of the epoxy matrix. The usefulness of the current study in developing new coating systems for high-performance applications is discussed.
