通过一种简便的方法,利用制革工业蛋白废弃物制备了一种稳定的胶原蛋白-超顺磁性氧化铁纳米粒子(SPIONs)的磁性纳米复合材料。螺旋状胶原纤维与球状SPIONs分子间的相互作用通过量热技术、显微技术和光谱技术来表征。该纳米复合材料展现出选择性吸油能力和磁跟踪能力,可应用于吸油方面。该纳米复合生物材料吸油后仍具有环境可持续性,经热处理后可形成双功能石墨纳米碳材料。这一研究提供了一种简便易行且可控的方法将生物质废弃物转化为多功能纳米材料。
Using a simple method, a stable collagen-superparamagnetic iron oxide nanoparticle (SPIONs) magnetic nanocomposite was prepared using leather industrial protein waste. The interaction between the helical collagen fibers and the spheroidal SPIONs is characterized by calorimetry, microscopy and spectroscopy. The nanocomposites exhibit selective oil absorption and magnetic tracking capabilities that can be applied to oil absorption. The nanocomposite biomaterials are still environmentally sustainable after oil absorption. After heat treatment, bi-functional graphite nano-carbon materials can be formed. This research provides an easy and controllable way to convert biomass waste into multi-functional nanomaterials.
