【 摘 要 】

Halloysite nanotubes (HNTs) are naturally occurring clay nanotubes mined from abundant mineral deposits, making it an easily accessible nanomaterial. Surface functionalization of HNTs with different components including metals, antibiotics, and bioactive compounds is of increased importance for their potential use in biomedical devices, antimicrobial surface coatings, drug delivery systems, radiation absorptive composites, elastomer composites, electronic components, and as industrial catalysts. We used a simple method for the fabrication of HNT-supported metal nanoparticles. Here, we report our strategy for controlled weight deposition of positively charged metal ions on negatively charged HNTs dispersed in an aqueous medium where metallization can be controlled using changes in voltage, solvent medium, time and other electrolytic parameters without the use of any toxic chemicals, expensive reagents or lengthy pre-processing steps. Our method offers a one-step and low-cost process that offers many advantages, including, the deposition of different metal oxides (Ag, Cu, and Zn) or dual metal coatings. HNTs act as a nanocarrier with an ability for sustained drug release and as a nanofiller with a record for improving the physical properties of polymers. When combined with metal-coated HNTs, this may lead to the creation of multi-functional applications in drug delivery, regenerative medicine and, tissue engineering.
