In this work, the changes caused by a chemical modification of the properties and chemical structures of lignin are studied. Lignin from a mixture of Eucalyptus globulus and Eucalyptus nitens obtained through the kraft pulping process was used. The lignin was isolated by acid precipitation and modified by a reaction with maleic anhydride. Maleated lignin (ML) was incorporated to recycled polystyrene (rPS) at 2, 5, and 10 wt-% by a melt-blending process. Fourier transformed infrared spectroscopy (FT-IR) was used to determine the ML structure, and the morphology of rPS/ ML composites was studied by scanning electron microscopy (SEM).Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to study the glass-transition temperature (T g ) and the thermal stability of rPS and rPS/ ML composites and were compared with virgin PS. The T g values of rPS and their composites were higher than those of the virgin PS. TGA revealed that the thermal stability of rPS with 2 and 5% of ML was slightly greater than that of the virgin PS. These results suggest that postconsumer PS can be used to obtain composite materials with good thermal properties.

“…Most of the attempts proved the antioxidant effect of lignin. The antioxidant and stabilizing characteristics of lignin have been studied in several polymers, but mainly in PE [153][154][155][156], PP [153,[157][158][159][160][161][162][163][164], PLA [165,166], poly(3-hydroxybutyrate) (PHB) [167], PCL [168] and in natural rubber [169,170].…”

“…Later the authors [155] extended their work in order to specify the role of lignin in the degradation of PP and PE under different conditions. They found that lignin acted as processing stabilizer, but initiated degradation 40 during long term heat stress or ultra-violet irradiation, when it was applied at large concentrations (above 10 wt%).…”

“…Various fundamental studies have been done to understand the effect of unmodified lignin on the physical properties of thermoplastic [12][13][14][15][16][17][18][19], thermosets [20], and rubbers [21]. Based on these studies, lignin has been documented to be a promising additive for stabilizing against UV degradation or thermo-oxidation [9,13,15,16,21].…”

Abstract:In this paper, we report the synthesis and characterization of ultra-high molecular weight polyethylene (UHMWPE)-lignin composites. During this study four different compositions, namely UHMWPE, UHMWPE-13 wt. % lignin, UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % lignin were fabricated by hot pressing. Detailed microstructural studies by scanning electron microscopy (SEM) showed that UHMWPE and UHMWPE-13 wt. % lignin had a uniform microstructure, whereas UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % lignin samples were riddled with pores. UHMWPE and UHMWPE-13% lignin showed comparable flexural strengths of~32.2 MPa and 32.4 MPa, respectively. However, the flexural strength dropped drastically in UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % samples to~13 MPa and~8 MPa, respectively. The tribology of UHMWPE-lignin composites is governed by the tribofilm formation. All the compositions showed similar µ mean values and the specific wear rates (WR) decreased gradually as the concentration of lignin in UHMWPE was increased.
