Thermoresponsive hydrogels have been studied in the past as self-healing and ultra-porous materials. Single-network (SN) and double-network (DN) hydrogels were synthesised in this research using acrylamide, acrylic acid, and alginate. Nano reinforcements were added only to increase the mechanical strength which is reported up to 300%. These DN hydrogels showed brilliant cooling performance showing 8-12°C lesser in a coated house for over 7 h with a single hydration cycle. Tough hydrogels were tested under direct sunlight on wooden and brick houses during the summer of Pakistan, where a 10-20°C temperature difference was reported. Thermographs and FTIR spectra showed that the ionic and covalent crosslinkers were responsible for the excellent robustness. DN hydrogel gave better strength and cooling effectiveness for a longer period than SN hydrogels. Carbon emission and electricity consumption can be reduced using DN hydrogels. These hydrogels can aid the industry of smart buildings and passive cooling.

“…Ɛ: the potential of Polanyi β: the coefficient of activity E: energy of sorption ln q e versus ϵ 2 - characteristic strong peak around 20 and another weak peak around 8 which become broader upon grafting due to partial destruction of the chitosan structure. [42,43] Likewise, the pure acrylic acid is reported in literature to have a distinguishable intense and broad peak at 17.2 with a shoulder at 35 , which is in good agreement with these findings. [44] However, this characteristic peak disappeared in S2 after grafting chitosan with 2-acrylamido-2-methylpropanesulfonic acid.…”

Exploring new and efficient adsorbents for the purification of water from heavy metals and organic waste to provide clean drinking water is highly demanded. Herein, the synthesis of polymeric materials based on grafting chitosan (Cs) by various acrylic monomers as acrylic acid (AA), 2‐acrylamide‐2‐methyl propane sulfonic acid (AMPS), and acrylamide (Am) namely S1, S2, or S3, respectively, using methylene bisacrylamide (NMBAm) as crosslinker was performed. The formed polymeric compound was characterized by utilizing Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X‐ray, and Brunauer–Emmett–Teller. It was determined that S2 possessed a higher specific surface area of 109.133 m2/g, which is higher than S1 (71.2553 m2/g) and S3 (62.8847 m2/g). The as‐prepared polymeric compounds were utilized for the removal of copper ions (Cu2+) and methylene blue (MB) from wastewater in the absence and presence of UV light irradiation. The kinetic study and the adsorption isotherms for the removal of Cu2+ and MB as organic pollutants using the as‐prepared polymeric compound were studied.

“…Cyt C, Lys and α-LA are small proteins, with comparable size (12–14 kDa), and BSA is a larger protein with 67 kDa. Many experimental studies have been conducted on the adsorption of Cyt C [ 37 , 38 , 39 , 40 , 41 , 42 , 43 ], Lys [ 33 , 34 , 44 , 45 , 46 ], α-LA [ 35 , 47 , 48 , 49 , 50 ] and BSA [ 36 , 47 , 51 , 52 ] on different materials. The use of different model proteins allows for studying the selectivity of the adsorption behavior of this polymer, specifically the influence of protein net charge and size [ 53 ].…”

Protein Adsorption Performance of a Novel Functionalized Cellulose-Based Polymer

Dicarboxymethyl cellulose (DCMC) was synthesized and tested for protein adsorption. The prepared polymer was characterized by inductively coupled plasma atomic emission spectrometry (ICP-AES), attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) and solid state nuclear magnetic resonance (ssNMR) to confirm the functionalization of cellulose. This work shows that protein adsorption onto DCMC is charge dependent. The polymer adsorbs positively charged proteins, cytochrome C and lysozyme, with adsorption capacities of 851 and 571 mg g−1, respectively. In both experiments, the adsorption process follows the Langmuir adsorption isotherm. The adsorption kinetics by DCMC is well described by the pseudo second-order model, and adsorption equilibrium was reached within 90 min. Moreover, DCMC was successfully reused for five consecutive adsorption–desorption cycles, without compromising the removal efficiency (98–99%).
