Abstract

Biobased nanocomposites and composite fibers were prepared from organosolv lignin/organoclay mixtures by mechanical mixing and subsequent melt intercalation. Two organically‐modified montmorillonite (MMT) clays with different ammonium cations were used. The effect of organoclay varying from 1 to 10 wt % on the mechanical and thermal properties of the nanocomposites was studied. Thermal analysis revealed an increased in T~g~ for the nanocomposites as compared with the original organosolv lignin. For both organoclays, lignin intercalation into the silicate layers was observed using X‐ray diffraction (XRD). The intercalated hybrids exhibited a substantial increase in tensile strength and melt processability. In the case of organoclay Cloisite 30B, X‐ray analysis indicates the possibility of complete exfoliation at 1 wt % organoclay loading. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

Two model coupling agents, water-dispersible (WDGP) and tetrahydrofuran (THF)-soluble graft copolymers (TSGP), were synthesized for carbon fiber/polycarbonate (PC) composites. WDGP contains a long polyacrylamide (PAAm) chain grafted on a PC backbone, whereas TSGP contains a short grafted PAAm chain.
