Halloysite, natural mineral with nanotube structure, loaded with iodopropynyl butycarbamate (IPBC) was prepared and its anti-mildew activity against mold and blue-stain fungi was investigated. With dimethyl sulfoxide (DMSO) intercalation, the loading content of IPBC could reach 34.6 wt% in halloysite nanotubes (HNT), and IPBC remained its crystal state inside HNT lumen. Through inhibition zone test and anti-mildew property test on bamboo, IPBC loaded HNT showed excellent anti-mildew activity against Aspergillus niger, Penicillium citrintim, Trichoderma viride and Botryodiplodia theobromae. In addition, the nano composites have significant sustained release behavior for IPBC, which could prolong IPBC release time from 3 to 62 h in ethanol. The nano composites with excellent anti-mildew activity as well as sustained release property show promising application of protecting wooden materials.

制备了具有纳米管结构的天然矿物埃洛石，并负载了碘丙炔基丁氨基甲酸酯（IPBC），并研究了其对霉菌和蓝变菌的抗霉活性。通过二甲基亚砜（DMSO）插层，埃洛石纳米管（HNT）中IPBC的负载量可达到34.6 wt％，并且IPBC在HNT管腔内保持其晶体状态。通过对竹子的抑菌圈试验和抗霉性能试验，IPBC负载的HNT对黑曲霉，西药青霉，木霉和木霉菌具有良好的抗霉活性。。此外，纳米复合材料对IPBC具有显着的持续释放性能，这可以将IPBC在乙醇中的释放时间从3 h延长至62 h。具有优异的抗霉菌活性和持续释放性能的纳米复合材料显示出有希望的应用来保护木质材料。
