Estudio de los diferentes tratamientos y modificaciones para la producción de celulosa nanofibrilar modificada

Abstract

[EN] Today society is focused on sustainability, for this reason is necessary to invest in the study of new materials. In this case, nanocellulose is a novel, recyclable and non-toxic material, which can be used to replace plastic and other materials that are not good for the environment. This thesis focuses its study on the analysis of the different modifications that are made to end up forming a modified nanofibrillar nanocellulose for use in applications such as biotechnology and biomedicine. The study begins with the obtaining of cellulose, studying its modifications to obtain the nanocellulose pulp, to later analyze in detail the pretreatments and chemical and biological treatments necessary for the creation of the fibrillar nanocellulose (CNF). Its properties and its applications are studied, to finally carry out the final modification to the nanofibers to introduce them mainly as reinforcement material in different matrices.
