Superabsorbent polymers (SAPs) are important in the health-care and personal care industries. Products like bed pads and diapers improve the comfort and sanitary conditions for people all over the world, with SAPs reaching yearly production volumes of ca. 2 million tons. However, recent sustainability issues have questioned the high negative footprint of polymers from nonrenewable resources. Biomacromolecules, especially when functionalized, have properties that make them an attractive alternative for the production of biobased SAPs. Proteins are a particularly interesting alternative due to their high variability and because of their relatively low price, being available as side streams from the agricultural industries. Due to the harsh extraction conditions, these side stream proteins are not competing with the food industry and alternative source-effective uses are advantageous in a circular bioeconomy. As the properties of a SAP material come from a combination of neutralized functional groups to promote polar liquid uptake and intermolecular cross-links to prevent dissolution, proteins offer unique opportunities due to their variability in polymerization. An increased understanding of the protein characteristics and how these can be tuned through functionalization is therefore a prerequisite for the successful development of a commercial biobased SAP that utilizes industrial and nontoxic wastes toward more sustainable products. This review focuses on proteins as biomacromolecules with relevant characteristics for superabsorbent functions, and discusses the opportunities that they may offer toward sustainable SAPs utilizing nontoxic chemicals and following the green chemistry principles.

“…Water resistance of ORW and FUW were displayed in Figure 8 , Figures S6 and S7 . Their swelling rates were recorded over time [ 31 ]. The results showed that the ORW absorbed water rapidly and expanded within 10 h; then, the swelling rate slowed down, and finally reached equilibrium at about 20 h. The ESR of ORW was 7.92.…”

A reversible photo-, thermal-, and pH-responsive high-performance functional wood with fluorescence has been prepared. The properties, structure, multi-response, fluorescence, water resistance, and corrosion resistance of original wood (ORW) and functional wood (FUW) were investigated with an X-ray photoelectron spectroscopy (XPS) spectrometer, a Fourier-transform infrared (FTIR) spectrometer, a N2 adsorption–desorption analyzer, an atomic force microscope (AFM), tensile tests, a scanning electron microscope (SEM), an ultraviolet–visible (UV–Vis) spectrophotometer, a fluorescence spectrometer, the equilibrium swelling ratio (ESR), and corrosion tests. The results of XPS, FTIR, N2 adsorption–desorption, and AFM exhibited that FUW was successfully prepared. Additionally, the results of the tensile test and SEM revealed that FUW had better mechanical properties than ORW, due to the filling of epoxy resin in the pores of the wood. Moreover, the UV–Vis and fluorescence spectra demonstrated that the introduction of epoxy resin induced multi-response and fluorescence functions to FUW. Furthermore, the data of ESR and corrosion test showed that the introduction of epoxy resin greatly improved the water and corrosion resistance of wood. This study provides ideas and methods for preparing novel high-performance multi-response FUW.

Hydrogels are smart materials with a high moisture content, elasticity, and stimuli to pH and temperature and are widely used in drug delivery, wound dressings, tissue engineering, parting materials, and sensors. However, a hydrogel with a multiresponsive feature is desired and challenging to produce. Here, a novel multiresponsive color-change hydrogel, including pH response, light response, and alcohol response, was successfully fabricated by introducing Michler’s hydrol blue (MHB) into a semicrystalline hydrophobically associated hydrogel. The color-change function is obtained by a transformation between MHB and protonated Michler’s hydrol blue (PMHB) deduced by nucleophilic attack processes. An excellent swelling performance of 2010% of the hydrogel was confirmed by swelling, time-dependent rewetting data, and differential scanning calorimetry (DSC) measurements. Its color change was obvious and fast, within 1 min, when exposed to ultraviolet (UV) light, alcohol, or pH change. In addition, the tensile strength of the hydrogel reached up to 0.9 MPa with loading MHB by 2.0%. The fluorescence and self-healing performances were verified to be good due to the presence of a large delocalized π-bond and hydrogen bonds. This material fabricated by a facile process might have potential applications in visual fluorescence sensors.
