Preparation method of halloysite-based nano-drug-loading material

The invention provides a preparation method of a halloysite-based nano-drug-loading material. The preparation method comprises the following steps: carrying out amino modification on carbon nanotubes,preparing carboxymethyl cyclodextrin, and grafting cyclodextrin onto the surfaces of the carbon nanotubes through an amidation reaction to obtain the halloysite-based nano-drug-loading material. Thedrug-loading microsphere has the characteristics of low cost, slow pesticide release speed, low loss rate, high utilization rate and no non-point source pollution, and can provide guidance for the research of pesticide sustained-release dosage forms. 本发明提出了一种埃洛石基纳米载药材料的制备方法，包括碳纳米管的氨基改性，然后制备羧甲基环糊精，最后通过酰胺化反应将环糊精接枝在碳纳米管表面制得埃洛石基纳米载药材料。该载药微球具有成本低廉、农药释放速度缓慢，流失率低、利用率高，且不会造成面源污染的特性，可对农药缓释剂型的研究提供指导。
