“…It is observed that the value of storage modulus (G’) increased with an increase in the angular frequency from 0.1 to 100 rad/s which indicated the increased elasticity of hydrogel. However, the addition of zeolite increased the degree and perfection of a cross‐linking network of hydrogels [30] . As a result, the value of storage modulus (G’) for zeolite‐loaded hydrogel (ZH‐4) is higher than zeolite unloaded hydrogel (ZH‐1).…”

In this research paper, various formulations of zeolite‐loaded carboxymethyl tamarind kernel gum (CMTKG) based hydrogels were synthesized and utilized as a potential adsorbent for the removal of crystal violet (CV) dye. The swelling capacity of all the synthesized hydrogels was investigated and the composition of hydrogel which exhibited maximum swelling was used for the characterization and dye removal experiment. The CV dye was chosen as a model dye for the dye removal experiment. The structure of zeolite and zeolite embedded hydrogel was elucidated by XRD, FTIR, FE‐SEM, EDX and elemental papping techniques. The adsorption experiment was investigated by varying the CV concentration, amount of hydrogel adsorbent, temperature, pH of the dye solution, adsorption time, and ionic strength. The Langmuir and Freundlich isotherm models were used to fit the adsorption data and it was observed that the data fitted well with the Langmuir model. Moreover, hydrogel‘s maximum dye adsorption efficiency was found at 123.60 mg g−1. The adsorption kinetic studies were followed by pseudo‐ first‐order and intraparticle diffusion kinetic models. In addition, regeneration studies were performed for the best adsorbent hydrogel using ethanol solvent and the result concluded the desorption efficiency of hydrogel (82 %) over four desorption cycles.

In recent years, hydrogels have been widely applied in daily life and industry. More and more fillers have been combined with hydrogel to broaden their fields of application and improve their mechanical properties. However, there are few works about zeolite‐based hydrogel composites via photopolymerization. Hence, in this work, it is reported that the fabrication of hydrogel composites containing zeolite (FAU‐13X ≈ 40 wt%) under mild photopolymerization conditions (visible LED light irradiation, at room temperature, under air, and without any monomer purification). Markedly, compared to pure hydrogel, the elastic modulus (G′) of hydrogel composite contains 10% FAU‐13X increased by more than 100%. When the zeolite content reached 40%, the water swelling ratio in mass reached 120%, and that in volume remained at 150%. In addition, 3D patterns with flat surface are obtained through direct laser write as a lithography technique. This means these hydrogel composites can be applied in the field of water absorption materials and 3D printing.

“…[42,[47][48][49][50][51][52] Hence, more and more works about zeolite filled composites or hydrogel composites have been reported in the literature and the resulting compos ites found increasing potential applications in the field of water adsorption, gas separation, and biomedical engineering. [48,53,54] In our previous work, [42] LTA5A and FAU13X, these two types of zeolite were used as particle fillers to be blended with poly ethylene glycol diacrylate (PEGDA) to obtain composites with different filler contents through photopolymerization. Com pared to the mechanical properties of pure PEGDA polymer, the storage modulus (G') of composite was enhanced and the volume shrinkage issue was also improved due to the presence of zeolite.…”

With the rapid development of photopolymerization, the search for new near-UV/visible light sensitive photoinitiating system (PIS) is the subject of intense research efforts. In this work, a new PIS (chalcone dye/amine/iodonium salt) could efficiently and simultaneously initiate the free radical photopolymerization (FRP) of PEGDA and the cationic photopolymerization (CP) of EPOX under irradiation of LED@405 nm to obtain interpenetrating polymer networks (IPNs). Then, the study on the photoinitiating abilities of the chalcone dye was examined to explain the chemical mechanisms through UV-visible absorption spectra, cyclic voltammetry, fluorescence approaches and electron spin resonance (ESR) spin-trapping experiments.Markedly, Chalcone is a class of natural dyes of flavonoids with potential low toxicity. Furthermore, this PIS was employed in the photopolymerization of LTA-5A zeolite filled interpenetrating polymer network composites (IPN, PEGDA/EPOX). Compared to the pure IPN, the depth of cure (DOC) for IPN with 50 wt% LTA-5A remarkably increased by ca. 90%, which was the first time reported that DOC could increase with the increase of the filler content.Compared to the storage modulus, tensile strength and Young's modulus of pure IPN, those of the IPN-composites containing 50 wt% LTA-5A increased by ca. 445 %, ca. 430 %, and ca. 2 580 %, respectively. By direct laser write (DLW), 3D patterns could be manufactured and those with high filler contents showed good water swelling property. Under hydrothermal stimuli, IPN composite with 50 wt% LTA-5A exhibited a good 4D printing behavior. Therefore, not only this chalcone dye has a good photoinitiation ability for photopolymerization, but also the resulting IPN composites prepared with the photoinitiating system containing this dye have potential applications for 3D/4D printing and composites preparation.
