Article Abstract
Cellulose has great potential in the field of piezoelectricity owing to its high crystallinity; however, it exhibits low processability and poor mechanical robustness. In this study, to enhance the applicability of cellulose-based piezoelectric materials, a robust cellulose-based piezoelectric elastomer with excellent piezoelectric properties was developed by cross-linking cellulose with polyrotaxane (PR). The effects of cross-linking on the mechanical properties and crystalline structures of the resulting elastomers were investigated. The ferroelectric and piezoelectric properties were evaluated from their polarization hysteresis loops and voltage generation characteristics. eHPCPR exhibited 2.7 times higher toughness (20.4 MJ m) than eHPC (7.57 MJ m). It also shows a power density 4.2 times higher (1.34 μW cm) than eHPC (0.321 μW cm). As a result, eHPCPR demonstrated piezosensitivity to mechanical vibrations in a variety of devices that require mechanical robustness. These results can inform the design and development of high-performance piezoelectric devices.

This paper explores the preparation and characterization of cellulose-based materials modified by hyperbranched polyamide (HBPA). Firstly, an alkaline urea solution was prepared to dissolve bacterial cellulose (BC) at low temperature. Then, after being modified by HBPA, BC hydrogel was hot pressed to form a cellulose-based film (BCF).

Flexible hybrid nanogenerators (HNGs) have received significant attention for their potential in harvesting mechanical energy to power portable and miniaturized portable devices. This work presents a method to fabricate flexible, durable and biodegradable electrospun polydopamine@barium titanate/cellulose acetate (PDA@BTO/CA) nanofiber films. This design integrates polydopamine (PDA) and piezoelectric barium titanate (BTO) nanoparticles within a flexible cellulose acetate (CA) matrix to enable self-powered wearable biomonitoring.

Integrating flexible piezoelectric nanogenerators (PENGs) into wearable and portable electronics offers promising prospects for motion monitoring. However, it remains a significant challenge to develop environmentally friendly PENGs using biodegradable and cost-effective natural polymers for mechanical energy harvesting and self-powered sensing. Herein, reduced graphene oxide (rGO) and barium titanate (BTO) were introduced into regenerated cellulose pulp to fabricate a composite porous film-based PENG.

In this work, we evaluated the flexoelectric and piezoelectric contributions to the overall macroscopic polarization in cellulose films. To this end, the flexoelectric μ and transverse effective piezoelectric e coefficients of cellulose films were determined using cantilever beam bending. The experiments were based on theoretical developments allowing to separate the flexoelectric from the piezoelectric contribution, represented by an effective flexoelectric coefficient, μ, depending on both e and μ.
