“…Mechanical properties are dependent on the crosslinking agent and chemical modification of the alginate structure, but polymer itself is characterized with good strength, elasticity, high viscosity, and stability. Alginate materials occur in three main structure types: hydrogel adjusting to the shape of the mold, fibers, and beads [ 170 , 171 ].…”

Modified alginates have a wide range of applications, including in the manufacture of dressings and scaffolds used for regenerative medicine, in systems for selective drug delivery, and as hydrogel materials. This literature review discusses the methods used to modify alginates and obtain materials with new or improved functional properties. It discusses the diverse biological and functional activity of alginates. It presents methods of modification that utilize both natural and synthetic peptides, and describes their influence on the biological properties of the alginates. The success of functionalization depends on the reaction conditions being sufficient to guarantee the desired transformations and provide modified alginates with new desirable properties, but mild enough to prevent degradation of the alginates. This review is a literature description of efficient methods of alginate functionalization using biologically active ligands. Particular attention was paid to methods of alginate functionalization with peptides, because the combination of the properties of alginates and peptides leads to the obtaining of conjugates with properties resulting from both components as well as a completely new, different functionality.

The cotton fabric, which is widely used as personal protective equipment, is vulnerable to droplets that may contain pathogens. Thus, the functionalization of cotton fabric is usually carried out to get the desired properties. Graphene-based materials have some interesting properties like hydrophobic, photothermal, and antibacterial properties that can be used to modify cotton fabric. This research has made a cotton fabric coated with graphene from coconut shells and polymethyl siloxane. Graphite was obtained from burning coconut shells, and the modified Hummers method was used to get a graphene oxide solution (GO). A graphene oxide layer on cotton fabrics was added by the dip-pad-dry process, followed by reduction using ascorbic acid to produce a reduced graphene oxide (rGO) and immersion of cotton fabrics with methyl trichlorosilane in n-hexane to produce a polymethyl siloxane (PMS) layer. Scanning electron microscope (SEM) and Fourier-transform infrared (FTIR) are used to determine the morphology and functional groups in rGO-PMS-coated cotton fabric. Contact angle measurements to determine the hydrophobicity of the rGO-PMS-coated cotton fabric, which exhibits hydrophobic properties with a contact angle of 146.3 °, which can show self-cleaning ability while preventing water droplets from entering the fabric. Antibacterial activity was carried out using the disc diffusion method against Staphylococcus aureus and delivered a good result. The rGO-PMS-coated cotton fabric also shows photothermal capability when irradiated with infrared lamps. HIGHLIGHTS Graphene is a material that has various properties that can be exploited for the functionalization of ready-to-use materials Waste derived from natural resources can be used as a source of graphene, which can reduce the cost of graphene production Cotton fabric as a functionalized material can adopt the combined properties of graphene and silane such as photothermal, antibacterial, and hydrophobic properties GRAPHICAL ABSTRACT
