Surface functionalization of graphene oxide with sulfonate group and subsequent grafting with polyurethane chains leads to the significant improvement in the properties of polymer and modified graphene as a filler. Modification of graphene oxide is revealed through spectroscopy while grafting of polymer chain over sulfonated graphene is confirmed through ¹H NMR and other techniques. Higher order of self-assembly phenomena is observed in nanohybrids as compared to pure polymer through greater interaction between polymer chain and sulfonated graphene. Significant improvement in corrosion inhibition phenomena is observed using nanohybrids at low concentration as compared to pure polymer indicating its superior efficiency as a corrosion inhibitor. Nanohybrids also exhibit better biocompatible nature in lower concentration of filler with considerable sustained release of drug vis-à-vis pure polymer suggest its potential to use as a biomaterial for tissue engineering applications.

功能化石墨烯标记的聚氨酯用于缓蚀剂和持续药物输送

具有磺酸盐基团的氧化石墨烯的表面官能化以及随后的聚氨酯链接枝导致聚合物和改性石墨烯作为填料的性能显着改善。通过光谱显示了氧化石墨烯的改性，而通过¹证实了磺化石墨烯上的聚合物链的接枝1 H NMR和其他技术。与纯聚合物相比，通过聚合物链与磺化石墨烯之间的更大相互作用，纳米杂化物中观察到了更高阶的自组装现象。与纯聚合物相比，使用低浓度的纳米杂化物可观察到腐蚀抑制现象的显着改善，表明其作为腐蚀抑制剂的优越效率。纳米杂化物在较低浓度的填料中也表现出更好的生物相容性，并且药物相对于纯聚合物而言具有相当大的持续释放，这表明它有潜力用作组织工程应用的生物材料。
