“…Nonetheless, cellulose is insoluble in most common solvents which restricts its processing. Therefore, cellulose is usually disintegrated into nanostructured cellulose for further application . As one kind of several nanocellulose, cellulose nanocrystals (CNCs) exhibit distinct properties, including high mechanical strength, aqueous dispersion stability, low thermal expansion coefficient, degradability and biocompatibility ,.…”

The new, sustainable, and pro‐environmental electrochromic devices (ECDs) have attracted tremendous attention due to the current issues regarding energy sources consumption and environmental pollution. A free‐standing composite film, consisting of cellulose nanocrystals (CNCs) as biological matrix, viologen, and KCl, was prepared by a casting method. Such a composite film is flexible and can be tailored into various shapes for patterned applications. The viologen/KCl/CNCs film was sandwiched between two indium‐tin oxide (ITO) glasses to construct viologen‐based ECDs. The performance of the viologen‐based ECDs did not depend on the organic solvent. ECDs based on four kinds of viologens with different substituent groups exhibited distinct coloration response. Besides the nature of the substituent groups attached to the bipyridine rings, the presence of CNCs is a crucial factor that affects the electrochromic performance of ECDs. The dimethyl‐substituted viologen ECD has a fast response time (10 s for bleaching and 7.3 s for coloring). And for the dibenzyl‐substituted viologen, a low voltage of −2.2 V can drive the coloration of its ECDs. The diethyl‐substituted viologen ECD exhibits 30 % transmittance variation and good coloring/bleaching stability. The ability to be tailored and degradability of the composite film provides a feasible strategy for the sustainability of electrochromic displays.

“…Mustapha et al 68 studied cellulose/PANI blends with the addition of glycerin as a plasticizer and obtained conductivity of 2.20 Â 10 À5 S/cm, a value very below of those obtained in this present article (Table 3). Furthermore, Latonen et al 69 synthesized a conductive ink with cellulose nanocrystals, PANI, and glycerol, obtaining conductivities of 30-60 S/cm. The conductivity values obtained in the previous paper for films with Cs and PANI (without glycerol) were 113.0 mS/cm for 80 mg/ml of PANI and 113.2 mS/cm for 100 mg/ml of PANI.…”

Chitosan (Cs) and polyaniline (PANI) were studied in this article for possible application as conductive and flexible films. Cs is a biodegradable polymer, that presents interesting properties as film applications. Otherwise, PANI is a semiconductor polymer with a wide range of applications. The films were produced by casting adding 30% glycerol and glutaraldehyde. The morphology, thermally, chemical structure, and electrical properties of films were obtained.Results showed the casting technique becomes possible to obtain self-standing films, with a chemical structure identical to precursor materials. Glutaraldehyde reacted to amine groups of terminal PANI chains, acting in the increase of electric conductivity and decrease of sheet resistance. The plasticizing effect of glycerol increased the spacing between Cs chains and facilitated the PANI dispersion. Therefore, glycerol and glutaraldehyde proved to be extremely efficient in increasing the electrical conductivity of blends.

“…Cellulose-based materials are also interesting materials for the production of pastes. Cellulose nanofibrils and cellulose nanocrystals modified with conductive polymers (Hoeng et al, 2017 ; Latonen et al, 2017 ), metal nanoparticles and carbon nanomaterials have been proposed as water-based pastes for screen-printing and ink-jet technologies (Couto et al, 2016 ; El Baradai et al, 2016 ). Moreover, ethyl cellulose (Hatala et al, 2019 ) and carboxymethyl cellulose (Barras et al, 2017 ), water-soluble derivatives of cellulose, are often used as dispersing agent.…”

The development of miniaturized electrochemical platforms holds considerable importance for the in situ analytical monitoring of clinical, environmental, food, and forensic samples. However, it is crucial to pay attention to the sustainability of materials chosen to fabricate these devices, in order to decrease the amount and the impact of waste coming from their production and use. In the framework of a circular economy and an environmental footprint reduction, the electrochemical sensor production technology must discover the potentiality of innovative approaches based on techniques and materials that can satisfy the needs of environmental-friendly and greener analytics. The aim of this review is to describe some of the printing technologies most used for sensor production, including screen-printing, inkjet-printing, and 3D-printing, and the low-impact materials that are recently proposed for these techniques, such as polylactic acid, cellulose, silk proteins, biochar.
