Synthesis and characterization of vinyl ester/inorganic layered material nanocomposites

Abstract

Vinyl ester/inorganic layered material nanocomposites were prepared from osmotic swelled clay which is a typical inorganic layered material. Inorganic layered material (montmorillonite clay type (CL120), Zinc Aluminum Layer Double Hydroxide (ZnAl LDH)) based nanocomposites have dominated the polymer literature and is one of the most significant areas of current and emerging interest. Disodium cocoamphodipropionate (K2) and sodium dodecylbenzene sulfonate (SDBS) were intercalated into montmorillonite and ZnAl LDH, respectively. Modified CL120 and ZnAl LDH dispersion morphology is confirmed by using X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FT-IR). The synthesized nanocomposites’ dispersion morphology is confirmed by XRD and TEM, and in order to evaluate the influence of these nanofillers, samples with different concentrations (1 and 3 phr) were dispersed in the matrix. The mechanical and shrinkage properties, dimensional stability, and print through phenomenon are expected to effectively help the development of wind blades.
