Summary: Cellulose paper is a promising substrate for smart sensing and electronic applications due to its flexibility, biocompatibility, and portability. By coupling cellulose paper with functional materials, its performance can be adjusted to meet specific requirements. This study demonstrates an efficient method to assemble cellulose paper with Polypyrrole (PPy) and Ag using the capillary forces of cellulose paper. The resulting PPy/Ag/cellulose paper bar shows sensitive responses to pH, gas, and mechanical stimuli, which can be attributed to the variation of bipolaron density and the modulation of electron transfer efficiency in the composite.

Summary: This study examines the 3D structuring of cellulose nanofiber foam-based ink and the transition of foam from insulator to conductor. The colloidal stability of the foam is crucial for producing a solid template for the synthesis of conducting polymers. Liquid foam ink is prepared by stirring a CNF suspension with an emulsifier, allowing for shear-thinning behavior and flexible design of structures through 3D printing. Conductive CNF foams are prepared via in situ polymerization on solid foam, with observed topological features and conductivity investigation.

Summary: This paper presents a theoretical investigation on a new actuator design using anisotropic colloidal particles grafted with stimuli-responsive polymer chains. These artificial muscles combine the osmotic actuation principle of hydrogels with the structural alignment of colloidal liquid crystals for directional motion. The study identifies the solubility, degree of polymerization, salt concentration, and grafting density of the polymer chains as important factors for actuator performance and tunability. Computational results suggest that the proposed material matches or exceeds the performances of natural muscles, providing guidelines for the realization of artificial muscles with predefined actuation properties.

Summary: Janus nanomaterials were functionalized with poly-lysine (PLL) and polydopamine (PDA) coatings on different sides, then added to poly (acrylic acid) (PAA)-based hydrogels to form self-healing nanocomposite hydrogels. The metal-ligand coordination between PLL, PDA, PAA chains, and metal ions contributed to the excellent mechanical properties and self-healing efficiency of the nanocomposite hydrogels. This study demonstrates the potential of Janus CNCs-PDA/PLL nanocomposites in the development of smart materials with self-healing ability.

Summary: One-dimensional nanomaterials of conductive polypyrrole (PPy) synthesized using lignocellulose nanofibrils (LCNF) as a template show high electrical conductivity and low cytotoxicity, making them promising for constructing bioelectronics. The PPy@LCNFs can be easily processed into thin coatings, flexible membranes, and three-dimensional cryogels. The dynamic control of doping/undoping process through an electric field enables both electronic and ionic conductivity. This study demonstrates the potential of PPy@LCNFs as a smart platform nanomaterial for interfacing bioelectronics.

Summary: Due to different extraction methods, CNCs have different surface groups with different degrees of substitution (DS), which affect the electrode properties of PPy/CNCs electrodes. The DS of CNCs sulfate groups has a significant effect on the electrode structure and electrochemical performance, while the DS of carboxylates does not. PPy/CNCs electrodes with carboxylated CNCs and a low DS of sulfate groups exhibit a porous and interconnected structure, while PPy/CNCs electrodes with carboxylated CNCs with a high DS of sulfate groups have a dense structure. The use of high-DS sulfate CNCs in dense PPy electrodes increases the charge storage capacity over cycles, showing improved structure and electrolyte perfusion.
