“…Ding et al [10] created biodegradable elastomers from biobased poly(ethylene glycol) (PEG) and citric acid (CA) at different molar ratios (PEG/CA 10:9). The reaction consists of two steps, the first step is a chain growth to a weight-average molecular weight (Mw) of about 1200 g/mol and the other step is crosslinking [10].…”

“…Tg lower than room temperature is consistent with an elastomeric material. The range of elongation at break was between 240 and 1505% and the ultimate tensile strength varied between 0.59-1.5 MPa, depending on the degree of crosslinking [10]. The modulus satisfies a part of the Dahlquist criterion (modulus is between 0.1-1 MPa).…”

A pressure-sensitive adhesive (PSA) is an adhesive system that is permanently tacky and adheres to a variety of surfaces with light pressure without phase changes. These adhesives are most commonly found in adhesive tapes such as the Scotch® tape or Post-it® notes. The majority of PSAs are petroleum-based products and usually not biodegradable. The amount of waste generated from these products is quite large as these products are considered disposable. The present review focuses on biodegradable elastomers and how they can be useful in PSAs. This review also covers some novel PSA systems that are biobased or biodegradable.

Usually, polyethylene glycol (PEG)‐based biodegradable solid‐solid phase change materials (BSSPCMs) are synthesized with isocyanate and PEG, removing water is necessary due to the sensitivity to water of isocyanate groups. In this study, a water insensitive synthetic scheme based on carboxyl and aziridinyl was employed to prepare PEG‐based BSSPCMs via solvent‐free bulk polymerization: First, a carboxyl modified polyethylene glycol was synthesized through esterification reaction of citric acid and PEG with the molar ratio 2:1. Then, the BSSPCMs were prepared based on an self‐curing and organic solvent‐free process, using trimethylolpropane tris(1‐aziridine propionate) as the cross‐linking agent. The chemical structure, crystalline properties, phase change properties, thermal stability, and reliability were investigated by Fourier transform infrared spectroscopy, X‐ray diffraction, polarizing optical microscopy, differential scanning calorimetry, thermogravimetric analysis, and accelerated thermal cycling testing, respectively. Solid–solid phase change behavior was testified by the leakage test. The biodegradation experiment was conducted to prove the biodegradability of solid–solid PCMs. The results indicated that BSSPCMs had a similar crystalline structure to PEG, and the crystal size was smaller than PEG. The phase change temperature of BSSPCMs was in the range of 25–65°C, and the latent heat of phase change materials (PCMs) was about 103–108 J/g. Moreover, the extent of supercooling of BSSPCMs was reduced. Thermogravimetric analysis and accelerated thermal cycling test results confirmed the considerable thermal stability and reliability of BSSPCMs. The prepared PCMs also exhibited a good biodegradability in the natural environment.
