CaCO₃blowing agent mixing method for biomass composites improved buffer packaging performance

Abstract

Biodegradable composites with an open-cell structure were developed to replace petroleum-based buffer packaging materials.

Pore structure evolution and adsorption behaviors of porous poly (vinyl alcohol) hydrogel prepared using Na2SO4 and CaCO3 as porogens

“…Furthermore, the pores of PVA‐Na were arranged more neatly and their pore walls were gradually thickened with the increasing Na 2 SO 4 soaking solution concentration (Figure 3B–D). These results might be due to the salting‐out effect of lower concentrations of Na 2 SO 4 solutions, which removed excess free water to produce a denser and regular hydrogel with small pores 26,36,37 . The higher the concentration of Na 2 SO 4 solution, the stronger the intermolecular hydrogen bonding of PVA chain.…”

Meanwhile, the strength of entire molecular chain skeleton increased as well as the pore walls of PVA-Na became thicker.…”

“…Calcium carbonate derivatives has high potential for use in biomedicine, biomedical engineering, biosensors, and controlled drug delivery as biodegradable and biocompatible materials (Sergeeva et al 2019, Niu et al 2022. Calcium carbonate microcapsules are used to improve the thermal stability and tensile strength of composite hydrogels (Gong et al 2019, Sun et al 2021, Arpornmaeklong et al 2023). In addition, it is used in hard tissue engineering for the production of porous CaCO3 scaffolds that have improved osteoconductive and mechanical properties, and in the production of porous hydrogels that release bioactive molecules (Sergeeva et al 2019, Arpornmaeklong et al 2023, Li and Jiang 2023.…”
