Application
La PEI se puede utilizar para funcionalizar nanotubos de pared simple (SWNT) para mejorar su solubilidad y biocompatibilidad a la vez que se mantiene la integridad estructural del SWNT original. Los SWNT funcionalizados covalentemente encuentran aplicación en la absorción de CO2 y la introducción de genes.
La PEI ramificada también puede utilizarse para modificar las propiedades superficiales de los adsorbentes. Las nanofibras de óxido de zirconio hidratado/PAN modificadas por PEI se utilizan para la desfluoración de las aguas subterráneas, ya que muestran una gran capacidad de adsorción de fluoruro y un amplio intervalo de pH de trabajo.
Features and Benefits
La PEI ramificada tiene una mejor capacidad de complejación y.tamponamiento.
