Modificación superficial de membranas de celulosa bacteriana

Abstract

La celulosa es uno de los biopolímeros más abundantes en la naturaleza y cuenta con características deseables como alta disponibilidad, origen renovable, bajo costo y excelentes propiedades mecánicas, por lo que se presenta como una alternativa económica y ambientalmente sostenible para sustituir fibras sintéticas en la producción de materiales compuestos [1]. Esta puede ser producida por microorganismos [2,3] o también puede ser extraída a partir de fuentes vegetales. Para incrementar la estabilidad de la celulosa a ambientes húmedos y favorecer su dispersión en matrices hidrofóbicas, es necesario modificarla a partir de tratamientos químicos o físicos específicos siendo uno de los más utilizados la acetilación [1,3] la cual es una de las metodologías de modificación más simples en la cual los grupos hidroxilo (-OH), en los cuales la celulosa es rica son reemplazados parcialmente por grupos acetilo (-COCH3)
