Abstract

Polystyrene is a type of plastic that is difficult to decompose naturally, leading to waste that contributes to environmental pollution. This study developed adhesive materials based on polystyrene waste to reduce environmental impacts while addressing the need for eco-friendly adhesives. The adhesives were prepared by dissolving polystyrene foam waste in gasoline and acetone with various compositions. The solvents with a composition ratio of gasoline and acetone of 100:0; 90:10; 80:20; 70:30; 60:40; and 50:50 were coded as A, B, C, D, E, and F. Tests were carried out to determine the solubility of polystyrene foam in various solvent compositions and the mechanical properties of samples, including shear force, shear strength, and strain (elongation). Paper, cardboard, and wood were used as gluing materials. The adhesive strength was also compared with that of commercial adhesives. The adhesive samples were then characterized using Fourier-Transform Infrared Spectroscopy (FTIR). The shear strength results obtained for samples code A, B, C, D, E, and F were 119.95 kPa, 103.68 kPa, 96.64 kPa, 124.56 kPa, 150.08 kPa, and 157.80 kPa, respectively. The findings showed that the adhesive sample coded F synthesized using a solvent composition of 50: 50 gasoline: acetone exhibited superior adhesive ability than other variations. This sample can potentially serve as a substitute for commercial adhesives that are suitable for bonding various materials.

Abstract

Green materials, such as microfibrillated cellulose (MFC), are increasingly used as fillers in polymer composites for academic and industrial applications. However, their inherent hydrophilic property limits compatibility with polymer matrix. This study employs an environmentally friendly cold plasma technique to modify the surface of MFC, improving its compatibility with the polymer. Plasma treatment was performed at a voltage of 60 V for 30 min by making three molar ratios (3:1, 4:1, and 5:1) between lauric acid as a hydrophobic precursor and anhydroglucose (AGU). The results indicate several changes in the modified MFC properties, as evidenced by the appearance of a new peak at a wavenumber of 1742 cm−1 (ester’s C=O) in FTIR spectra, indicating successful plasma-induced grafting. XPS results also confirm the formation of O–C=O bond at a binding energy of 289.3 eV. The optimum conditions were obtained at a molar ratio of 4:1 (lauric acid:AGU). There was a decrease in the hydrophilic property of MFC, indicated by an increase in the water contact angle from 50.16° to 71.26°. Moreover, the surface tension difference between MFC and polypropylene was significantly reduced from 136.99 to 47.51%, suggesting improved compatibility.
