Development of cellulose-based conductive fabrics with electrical conductivity and flexibility

Abstract

This study aimed to produce cellulose-based conductive fabrics with electrical conductivity and flexibility. Bacterial cellulose (BC) and three chemical cellulose (CC), namely methyl cellulose (MC), hydroxypropyl cellulose (HPMC) and carboxymethyl cellulose (CMC) were in situ polymerized with aniline and the four conductive cellulose fabrics were compared and evaluated. Matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy analysis confirmed that three CC-PANI composites displayed longer and more stable polymerization pattern than BC-PANI because of the different polymerization method: bulk polymerization for BC-PANI and emulsion polymerization for CC-PANI, respectively. The electrical conductivity of BC-PANI and CC-PANI were ranging from 0.962 × 10 −2 S/cm to 2.840 × 10 −2 S/cm. MC-PANI showed the highest electrical conductivity among the four conductive cellulose fabrics. The flexibility and crease recovery results showed that MC-PANI had the highest flexibility compared to BC-PANI, HPMC-PANI, and CMC-PANI. These results have confirmed that the electrical conductivity and flexibility were influenced by the type of cellulose, and MC-PANI was found to have the best performance in the electrical conductivity and flexibility.

Comparative study on the physical entrapment of soy and mushroom proteins on the durability of bacterial cellulose bio‐leather

“…Generally, a sample with good crease recovery can return to its original state without being damaged (Kim et al 2020a). Thus, it can be assumed that a sample with a high crease recovery value has good durability (Kim et al 2020a). According to Fig.…”

“…BC is an eco-friendly cellulose material produced by Acetobacter xylinus (Kim et al 2020a). Since BC is made of a fibrous three-dimensional nanostructure, it has excellent advantages as a bio-leather: It possesses high purity, high crystallinity and polymerization degree, and good water-holding capacity (Kim et al 2020b); Altering the fermentation conditions can result in BC with excellent moldability, biodegradability, and biocompatibility (Song et al 2020); Moreover, unlike animal leather, additional processes such as tanning and graining are not necessary for BC bio-leather.…”

Production of coffee-dyed bacterial cellulose as a bio-leather and using it as a dye adsorbent

“…The FT-IR spectra are demonstrated in Fig 5, and the characteristics of the BC-COF peaks are listed in Table 1. As shown in Fig 5, the FT-IR spectra of BC-COF and original BC displayed peaks at 3347 cm -1 and 3448 cm -1 , respectively, which were attributed to the -OH stretching vibrations of the hydroxyl groups of cellulose and coffee [48][49][50]. These peaks indicated that the chemical structure of BC remained unchanged after dyeing with coffee [2].…”
