| Summary: | In this study, the physical, morphological, mechanical and thermal properties of
furfuryl alcohol/2-ethylhexyl methacrylate/halloysite nanoclay wood polymer
nanocomposites (FA-co-EHMA-HNC WPNCs) were investigated. FA-coEHMA-HNC WPNCs were prepared via an impregnation method and the
properties of the nanocomposites were characterized through the weight percent
gain, Fourier transform infrared (FT-IR) spectroscopy, scanning electron
microscopy (SEM), three-point flexural test, dynamic mechanical thermal analysis
(DMTA), thermogravimetric analysis (TGA), differential scanning calorimetry
(DSC) analysis and moisture absorption test. The weight percent gain in the 50:50 FA-co-EHMA-HNC WPNC was the highest compared with the raw wood (RW)
and other WPNCs. The FT-IR results confirmed that polymerization took place in
the nanocomposites, especially 50:50 FA-co-EHMA-HNC WPNC, which had a
reduced amount of hydroxyl groups. The SEM results revealed that the 50:50 FAco-EHMA-HNC WPNC had the smoothest and most uniform surface among all of
the nanocomposites. The 50:50 FA-co-EHMA-HNC WPNC showed the highest
flexural strength and modulus of elasticity. The results revealed that the storage
modulus and loss modulus of the FA-co-EHMA-HNC WPNCs were higher and the
tan δ of FA-co-EHMA-HNC WNPCs was lower compared with the RW. The FAco-EHMA-HNC WPNCs exhibited the higher thermal stability in the TGA and
DSC analysis. The 50:50 FA-co-EHMA-HNC WPNC exhibited remarkably lower
moisture absorption compared with the RW. Overall, this study proved that the
ratio 50:50 FA-co-EHMA ratio was the most suitable for introduction in the in the
RW. |
