In addition, the higher C content in HM15 when compared with HM10 reveals a higher amount of HTAB component in the organoclay, as shown in the embedded table in Fig.
001] spacing indicates the effective intercalation of HTAB cations into the MMT layers (30).
The incorporation of higher amount of HTAB during the modification process improved the exchange efficiency.
This is attributed to the improved filler--matrix interactions through the interactions between the amine groups in HTAB and the carbonyl groups in PBS by forming hydrogen bonding.
The presence of trimethyl groups in HTAB caused a steric hindrance effect on the adjacent clay layers, and facilitated the filler dispersion when an external shearing force was applied during mixing process (22), (35).
001] spacing of HM is lower, the bulky methyl side chains of HTAB facilitate the diffusion of polymer chains inside clay galleries when shearing force was applied during melt-mixing process, further spreading the clay layers apart (22).
HTAB] (5% organoclay with HTAB and 5% PDMS V-Si 21 containing sample) have been improved.
HTAB] (5% organoclay with HTAB and 10% PDMS V-Si 21) indicates the accumulation of siloxanes near the surface (Fig.
Epoxy nanocomposites containing PDMS V-Si 21 have been synthesized by microwave curing using sodium montmorillonite modified by dodecyl-, hexadecyl-, octadecyl-amines, and HTAB.
