"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"
