In this research, a multifunctional strain sensor based on gluten/guar gum (GG) copolymer was developed. The effects of gluten/GG blended ratios on the mech. and elec. properties, self-adhesion, self-healing, remolding, self-powered and long-term stability of the strain sensors were studied. Among tested substrates, the gluten/GG blend indicated a strong adhesion to wood and paper substrates and showed a maximum adhesive strength at 1.5 wt% of GG in the copolymer (gluten/GG-1.5%). The adhesive strength of gluten/GG-1.5% decreased in the acceptable range when it was applied in 10 repeated adhesion cycles. The gluten/GG-1.5% exhibited a high elec. conductivity of 0.12 S/m and stretchability of 465%. The gluten/GG-based sensor containing glycerol showed long-term stability of self-healing, remolding, and self-powered ability when stored for 7 days, whereas the self-adhesive ability decreased with increasing storage time. The self-adhesive gluten/GG-1.5% was used to monitor human limb movements, which showed remarkable sensitivity during the storage time of 3 days. Such properties suggested a potential use of smart strain sensors with multifunctional capabilities for applications in wearable electronic devices. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Quality Control of Glyceryl monostearate).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Quality Control of Glyceryl monostearate
