This search aims to study the effect of alumina nanoparticles with a diameter (100 nm) on the properties of Poly Acryl amide (PAM) with different weight percentage of alumina nanoparticles including (0.1, 0.6, and 0.8)% wt. PAM with 0.1 wt. was made by using a hot plate magnetic stirrer to dissolve 10 g of poly acrylamide powder in 90 g of di-ionized distil water for 4 hours. The resultant solution was divided into four portions, each with a volume of 25 mL. Alumina nanoparticles in various ratios (0.0, 0.1, 0.6, and 0.8) were combined separately with each solution to produce four nano fluid solutions with varying alumina nanoparticle contents based on each weight %. The nano composited membranes were made using the hand casting method for nanocomposites samples, which involved pouring the prepared solution into a suitable plastic mold, leaving it to cure for 24 hours, and then cutting the resulting thin film according to each test. Tensile strength, Young's modulus, elongation, and toughness were studied by tensile test. As well as, Fourier transition infrared radiation (FTIR) test for studying the physical and chemical bonds between the poly Acryl amide and alumina nanoparticles was performed. Scan electron microscopy was used to study the morphology of the samples. The contact angles of samples were tested to limit the hydrophilicity behavior of these samples. Concluded from this paper the adding alumina nanoparticles to PAM matrix leads to enhance the mechanical properties of resultant nanocomposites, tensile strength increases from 2.25 MPa to 8 MPa with increasing alumina nanoparticles from 0 to 0.8% wt. respectively, Young's modulus also increased from 13 t0 20 MPa for the same previous ratios. Toughness increases to 3 kJ/cm2 for the higher weight ratio of alumina nanoparticles (0.8 %) wt. On the other hand the adding alumina nanoparticles lead to enhance the contact angle of PAM surface from 55 o to 60 o and it has hydrophilic behavior. This results refers to use the resultant nanocomposites as a coating for hydrophilic with high mechaninical properties requirement's. [ABSTRACT FROM AUTHOR] |
