Abstract
Cellulose is one of the most abundant, naturally
occurring biopolymers on Earth with remarkable properties
and thus "naturally" attractive for diverse applications.
In recent years, nanocelluloses received renewed interest
among cellulosic materials due to their nanosized
dimension, high stiffness of crystalline domains,
and-depending on source and processing conditions-liquid
crystallinity, high aspect ratio, and high specific
surface area. Given their broad range of physical
appearance, nanocelluloses display a likewise broad range
of applicability with the potential to replace plastics,
serve as templates for chiral nematic photonics, support
catalysts as high surface scaffold, and aid in tissue
healing. Their specific surface chemistry further offers
various ways for covalent and supramolecular
modification. In many cases, such modification is even
necessary to enhance compatibility with hydrophobic
components and to ease processing. This article addresses
both the extraction of nanocelluloses from plant cells
and their use in material design utilizing supramolecular
chemistry. These include supramolecular interactions with
the nanocellulose surface, hydrogen bonding,
metallosupramolecular and protein-mediated interactions,
and supramolecular polymer-polymer entanglements of
surface-grafted polymer brushes as well as combinations
of the aforementioned.
