Polyurethane Foam Reinforced with Fibers Pineaplle Crown Biocomposites for Sorption of Vegetable Oil
Isabella Loureiro Muller Costa,Francisco Maciel Monticeli,Daniella R. Mulinari 한국섬유공학회 2020 Fibers and polymers Vol.21 No.8
The concern in reducing the environmental impacts caused by human interference is increasing. Thus, theobjective of this study was to generate a sustainable solution for sorption of vegetable oil. It was developed and characterizedbiocomposites obtained from polyurethane derived from castor oil reinforced with fibers from the crown of pineapple forsorption of vegetable oil. The biocomposites were obtained by mass mixing the polyol with the prepolymer (1:1) andreinforced with 5 to 20 % (wt/wt) pineapple crown fiber in 18 and 35 mesh granulometry. The biocomposites and purepolyurethane were characterized by scanning electron microscopy (SEM), optical microscopy (OM), X-ray Diffraction(XRD), porosimetry, contact angle, and density. Sorption tests were carried out on the biocomposites and pure polyurethane(PU). The sorption capacity of the biocomposites was evaluated as a function of the fiber content inserted in the matrix. Results of the sorption tests showed that the biocomposites reinforced with fibers of 18 mesh (20 % wt) presentedapproximately twice the sorption capacity when compared to pure PU and others biocomposites results, due to high porositycombined with high surface area, which influenced directly in the oil sorption. Response surface methodology (RSM)tecnique confirmed the influence fibers granulometry and content on oil sorption.
