When nanocellulose meets hydrogels: the exciting story of nanocellulose hydrogels taking flight

Abstract

The rapid development of nanocellulose and hydrogels has contributed to the development of renewable smart material technologies in recent years. Based on the excellent renewable and biodegradable properties of nanocellulose,...

Robust hydrogel sensor with good mechanical properties, conductivity, anti-swelling ability, water tolerance and biocompatibility

“…Electrically conductive hydrogels with the ability to transduce diverse deformations and/or motions into electrical signals have drawn considerable attention in various fields, such as wearable devices, [1][2][3][4][5][6] biomedical applications, 3,4 electronic skin, 5,6 flexible supercapacitors, 7,8 and soft robots. 9,10 The conductivity of the conductive hydrogels is achieved via introducing conductive additives into the hydrogels.…”

Constructing robust and recyclable self-powered polysaccharide-based hydrogels by adjusting Zn2+/Li+ bimetallic networks

“…5–8 Indeed, these unique structural characteristics have opened up vast application prospects for hydrogels in various fields, including drug delivery, tissue engineering, wearable devices, and energy storage. 9–11 Particularly, in recent years, conductive hydrogels have demonstrated significant potential in the realm of self-powered wearable devices, represented by piezoelectric nanogenerators, frictional nanogenerators, thermoelectric generators, self-powered flexible batteries, etc. 12–15…”

Efficient adsorption and separation of Mn–Cu–Cd composite pollutants using MOF-based calcium alginate composite hydrogels

“…22 Thus, hydrogels are regarded as highly promising carriers for MOFs. Meanwhile, based on the consideration of environmental protection and cost, bio-based hydrogels such as cellulose, 23 chitosan, 24 and sodium alginate (SA) 25 have received extensive attention. Among them, SA is a natural anionic polymer material derived from brown seaweed.…”
