| Özet |
| Paper and paper-based compounds are frequently coated with various polymeric chemicals to improve their qualities, ranging from surface roughness to printability. Different biological derivatives of polymers, including as starch, chitosan, and cellulose precursors, are routinely utilized to improve paper qualities via various coating approaches. In this investigation, alginates (Als) of varying molecular weights were combined with zinc oxide (ZnO), and the produced compositions (1/1, 1/0.5, 1/0.25) were applied to the filter paper surface using a simple bar coating process. Control and Al/ZnO-coated papers’ density, degradation versus time, oil absorption performances, FTIR spectrum, dry-wet strength, COBB values, air permeabilities, antibacterial activities and SEM images were evaluated for determining Al and Al/ZnO-based coating solutions’ efficiencies. The density values of the papers were found to range from 42.10 g/cm³ to 46.75 g/cm³. The inclusion of ZnO reduces liquid absorption efficiency, which is consistent with the degradation results. The use of ZnO in the coating solution enhanced both the dry strength and water absorption capabilities, leading to strength performance improvements from 0.2134 kN m/g to a range of 0.3220 kN m/g to 0.3652 kN m/g. Contrastly, wet strength performances decreased to 0.0205 kN m/g-0.0262 kN m/g from 0.45 kN m/g. In general, both strength and antibacterial performances show that these papers can be candidates for food packaging material for low-weighted dry substances. |
