Gelatin/montmorillonite bionanocomposite hydrogels containing 0, 5 and 10 wt.% of montmorillonite were prepared via two different techniques, either a cooling or drying method. In addition, gelatin/polyvinyl alcohol/montmorillonite bionanocomposite hydrogels having gelatin/polyvinyl alcohol ratios of 1/1, 1/2 and 2/1, loaded with 0, 5 and 10 wt.% of montmorillonite, were prepared via a cyclic freezing-thawing technique. The microstructural properties of both types of the prepared bionanocomposite hydrogels were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The gel fraction, swelling behavior and drying kinetics of all prepared bionanocomposite hydrogels were also studied. The XRD and SEM results showed a porous structure with a possible exfoliated morphology for both types of the prepared bionanocomposite hydrogels. In addition, the gel fraction of the bionanocomposite hydrogels increased and a more entangled and crosslinked network with a decreased pore size was obtained by increasing the loading level of montmorillonite for both types of the bionanocomposite hydrogels. The swelling ratio and drying rate of both types of the bionanocomposite hydrogels could be increased by decreasing the PVA portion or MMT loading level, while the swelling and drying ability of the gelatin/montmorillonite bionanocomposite hydrogels prepared via the cooling method was higher than those of the corresponding samples prepared via the drying method.

通过两种不同的技术，即冷却或干燥方法，制备了含有0、5和10重量％的蒙脱石的明胶/蒙脱石的复合纳米水凝胶。此外，通过循环冷冻制备了明胶/聚乙烯醇比率为1 / 1、1 / 2和2/1的明胶/聚乙烯醇/蒙脱土复合材料水凝胶，其中负载了0、5和10 wt。％的蒙脱土。解冻技术。使用X射线衍射（XRD）和扫描电子显微镜（SEM）研究了两种类型的制备的纳米复合水凝胶的微观结构特性。还研究了所有制备的生物纳米复合水凝胶的凝胶分数，溶胀行为和干燥动力学。XRD和SEM结果显示出两种类型的制备的生物纳米复合水凝胶的多孔结构可能具有剥落的形态。另外，通过增加蒙脱石对两种类型的生物纳米复合水凝胶的负载水平，生物纳米复合水凝胶的凝胶分数增加，并且获得了更纠缠和交联的网络，其孔径减小了。降低PVA含量或MMT负载量可以提高两种类型的生物纳米复合水凝胶的溶胀率和干燥速率，而通过冷却法制备的明胶/蒙脱土生物纳米复合水凝胶的溶胀和干燥能力要高于其。通过干燥方法制备的相应样品。通过增加蒙脱石对两种类型的生物纳米复合水凝胶的负载量，可以使生物纳米复合水凝胶的凝胶分数增加，并获得更纠缠和交联的网络，并且孔径减小。降低PVA含量或MMT负载量可以提高两种类型的生物纳米复合水凝胶的溶胀率和干燥速率，而通过冷却法制备的明胶/蒙脱土生物纳米复合水凝胶的溶胀和干燥能力要高于其。通过干燥方法制备的相应样品。通过增加蒙脱石对两种类型的生物纳米复合水凝胶的负载量，可以使生物纳米复合水凝胶的凝胶分数增加，并获得更纠缠和交联的网络，并且孔径减小。降低PVA含量或MMT负载量可以提高两种类型的生物纳米复合水凝胶的溶胀率和干燥速率，而通过冷却法制备的明胶/蒙脱土生物纳米复合水凝胶的溶胀和干燥能力要高于其。通过干燥方法制备的相应样品。
