“…They have unique and unusual characteristics because of their small size and large specific surface area. Due to their characteristics, metallic nanoparticles have found use in a number of fields, including catalysis, electronics, filtration, purification, food packaging, medicine, and photonics [3][4][5][6][7]. The idea of using silver nanoparticles as an antibacterial agent is quite recent.…”

In this study, a chemical procedure was used to produce nano-silver particles (reduction method). At different molar concentrations, reactive substances including sodium citrate and silver nitrate were employed. A smaller average size is produced by mixing (sodium citrate: silver nitrate) at an optimal molar concentration of (1:20). To determine the Zeta Potential and (PDI) of the generated silver nanoparticles, the (DLS) Zetazaser instrument was employed. To examine the structural and component of produced silver nanoparticles, X-ray diffraction and EDX techniques are applied. The outcomes showed that this approach generated stable, homogenous nano silver particles with an average size of 58 nm and a PDI factor of 0.055. The electrospinning process was used to create different nano-fiber diameters of poly vinyl chloride (PVC) nanofibers reinforced with silver nanoparticles from solution under strict working conditions, including solution parameters (viscosity, temperature). Gram-positive and gram-negative microorganisms were used to test the antibacterial activity of tissue generated with silver nanoparticles. According to the findings, both species of bacteria were effectively suppressed to a degree of 99.99 percent by the tissue that was created.

“…Materials' hydrophobicity behaviour is classified into two types involve those that are hydrophilic and hydrophobic 5,6 In contrast to hydrophobic materials, which have self-cleaning surfaces and tend to reject water, hydrophilic materials tend to form hydrogen bonds with water and have a contact angle of less than 90 degrees [7][8][9] . The primary synthesis techniques for nanomaterial-based membranes are phase inversion, sintering, layer-by-layer, interfacial polymerization 10 and electrospinning [10][11] . Recent studies have shown that the electrospinning approach is a flexible and efficient method to create nanofibrous membranes, particularly polymer membranes with controllable compositions and structures [12][13][14] .…”

“…The nanomaterials are added to the basic materials in order to enhance their properties and get additional qualities for the new nanocomposites materials that are produced. The addition of nanoparticles improved the mechanical, thermal, optical, and antibacterial properties of nanocomposites because dimensionality significantly influences material properties [1][2][3][4][5][6] Water-repellent or water-repellent qualities are how materials react to water [7][8] . In contrast to hydrophobic materials, which tend to reject water and have self-cleaning surfaces, hydrophilic materials tend to form hydrogen bonds with water and have a contact angle of less than 90 degrees [9][10] .…”

The aim of this investigation is to determine how different weight percentages of alumina nanoparticles, including 0.02, 0.04, and 0.06 percent wt, affect the physical characteristics of Poly Acrylamide (PAAM). Using a hot plate magnetic stirrer, 10 g of poly acrylamide powder was dissolved in 90 g of di-ionized distillate water for 4 hours to produce PAAM with a concentration of 0.11 g/ml. Four sections of the resulting solution, each with a volume of 20 ml, were created. Each solution was added independently with alumina nanoparticles in different ratios 0.0, 0.02, 0.04, and 0.06 to create four nano fluid solutions with different alumina nanoparticle contents based on each weight percent. The hand casting process for nanocomposites samples, which entailed pouring the prepared solution into an appropriate plastic mold, allowing it to cure for 24 hours, and then cutting the resulting thin film according to each test, was used to create the nano composited membranes. The tensile test was used to study tensile strength, Young's modulus, elongation, and toughness. Additionally, a test using Fourier transition infrared radiation (FTIR) was conducted to examine the chemical and physical connections between polyacrylamide and alumina nanoparticles. The morphology of the materials was examined using scan electron microscopy. The contact angles of samples were tested to limit the hydrophilicity behavior of these samples. To control the hydrophilicity behavior of these samples, the contact angles of the samples were evaluated. The results showed that including alumina nanoparticles into the PAAM matrix improves the mechanical characteristics of the resulting nanocomposites. Tensile strength increases from 1 GPa to 2.5 GPa with an increase in alumina nanoparticle content from 0 to 0.06 percent wt. For the same prior ratios, Young's modulus likewise increased, rising from 1.3 to 2 GPa. For the higher weight ratio of alumina nanoparticles (0.04 percent wt), toughness rises to 240 J/cm2. On the other hand, the addition of alumina nanoparticles increased the PAAM surface's contact angle from 55 degrees to 67 degrees, and it exhibited hydrophilic behavior
