| Özet |
| We report the preparation of poly(styrene-co-divinylbenzene-co-2-ethylhexyl acrylate) polyHIPE composite foams through the use of silane functionalized cellulose nanocrytals (fCNCs). By varying the concentration of methacryloxypropyltrimethoxysilane (MPS) coupling agent during functionalization and the amount of fCNCs loading in the precursor emulsion it is demonstrated that fCNCs can be used for tuning of morphological and mechanical properties, as well as thermal stability. Incorporation of fCNCs demonstrated a significant influence on the emulsion stability. Moreover, variation of average cavity diameters of the composite foams prepared with the same amount of fCNCs but containing different concentrations of MPS displayed the importance of MPS concentration. In terms of mechanical features, fCNCs loading improved the compression modulus of the obtained foams. The results also showed that fCNCs prepared by using low concentration of MPS were less effective on the compression modulus. While the polyHIPE/fCNCs composite foam prepared with 1.0 wt% of fCNCs (containing 60 mM MPS) showed 33% higher compression modulus as compared to the neat polyHIPE foam, the increase in the compression modulus was much less for the composite foams prepared by using 20 mM MPS. In addition, the initial temperature of decomposition was also 51.6 °C higher than the neat polyHIPE foam. |
