A fungicide, hexaconazole was successfully intercalated into the intergalleries of zinc/aluminum-layered double hydroxide (ZALDH) using the ion-exchange method. Due to the intercalation of hexaconazole, the basal spacing of the ZALDH was increased from 8.7 Å in ZALDH to 29.4 Å in hexaconazole-intercalated ZALDH (HZALDH). The intercalation of hexaconazole into the interlayer of the nanocomposite was confirmed using the Fourier-transform infrared (FTIR) study. This supramolecular chemistry intercalation process enhanced the thermal stability of the hexaconazole moiety. The fungicide loading was estimated to be 51.8%. The nanodelivery system also shows better inhibition toward the Ganoderma boninense growth than the counterpart, free hexaconazole. The results from this work have a great potential to be further explored for combating basal stem rot (BSR) disease in oil palm plantation.

（己康唑锌/铝双层氢氧化物纳米复合材料）杀菌剂纳米传递系统的合成，用于控制油棕中的灵芝病

使用离子交换方法将杀菌剂六康唑成功插入到锌/铝层双氢氧化物（ZALDH）的化合物间。由于六康唑的插入，ZALDH的基础间距从ZALDH中的8.7Å增加到六康唑插入的ZALDH（HZALDH）中的29.4Å。使用傅里叶变换红外（FTIR）研究证实了六康唑插入纳米复合材料的中间层中。这种超分子化学插入过程增强了六康唑部分的热稳定性。杀菌剂的负载量估计为51.8％。纳米递送系统还显示出对灵芝波宁菌的更好抑制作用增长超过对口，游离己康唑。这项工作的结果具有巨大的潜力，可进一步用于抗击油棕人工林中的基茎腐烂（BSR）病害。
