Assembly of Polyacrylamide-Sodium Alginate-Based Organic-Inorganic Hydrogel with Mechanical and Adsorption Properties

Abstract: Hydrogels have been widely used in water purification. However, there is not much discussion and comparison about the effects of different nanofillers on the reinforcement and adsorption performances of hydrogels, which can be subjected to rapid water flow and possess strong adsorption ability. In this work, polyacrylamide (PAAM)-sodium alginate (SA) interpenetrating polymer network-structured hydrogels were prepared by in situ polymerization. PAAM formed the first flexible network and SA constructed the secon… Show more

“…In order to achieve multi-function for nanofiber-based food packaging materials, various fillers have been added into polymer substance, especially inorganic fillers that possess conductivity, magnetism, antibacterial property, etc. [98][99][100][101]. Then, a nanofiber-based food packaging material could be prepared through the electrospinning technique.…”

“…e adsorption capacity of the fabricated polymer-CNT composite was 1.28 times higher than that of polymer composite only. Figure 7 simply summarizes the synthetic route of this polymer-CNT composite, its morphological structure, and its adsorptive characteristics [37]. Also in another study, polyaniline grafted multiwalled-CNT composite was prepared by an oxidation polymerization process.…”

“…Polymer carbon nanotubes (CNTs) nanocomposites (PCNT) are very attractive from research and application points of view, because they can elucidate important properties when the concentration of nanoparticles reaches the percolation threshold, which is the minimum CNT content that produces the conductive networks in nanocomposites [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Long and thin CNTs normally introduce a low percolation threshold, producing a conductive nanocomposite by incorporation of very low CNT content [16].…”
