“…The addition of the "high aspect ratio" layered silicate into GF-12 leads to an increase of hardness (decrease in indentation depth) in comparison with the neat GF-12. The nanohardness results were found to be in close agreement with the work carried out by other studies (Aldousiri et al, 2011;Dhakal, Aldousiri, Zhang, Alhubail, & Bennett, 2015). …”

“…Likewise, Aldousiri et al (Aldousiri, Dhakal, Onuh, Zhang, & Bennett, 2011) carried out a study of the nanoindentation of spent polyamide-12 and the PA-12/nanocomposite. It was found that the addition of layered silicate led to increases of up to 116% and 73%, respectively of n ano-hardness and modulus, compared to the unreinforced polymer.…”

This work is an attempt to improve the thermal and nanoindentation behaviours of recycled Glass-Filled Polyamide-12 (GF-12) by adding layered Silicate (Nanoclay) as a reinforced filler. Differential Scanning Calorimetry (DSC) and Nanoindentation tests were conducted to study the effect of various loading levels (0-7 wt. %) of Nano-layered silicate on the thermal and nanohardness behaviours of GF-12 and its nanocomposites. Wide Angle X-ray Diffraction (WAXD) was employed to characterise the nanostructure of material and determine the intercalation/exfoliation for layered silicate in a GF-12 matrix. This study reveals that the layer silicate has a positive effect on the hardness results. Nanoindentation results showed remarkable improvement when layered silicate was added to recycled GF-12. The Glass transition (T g ) and crystallization (T c ) temperatures showed a slight improvement over the base polymer by the incorporation of layered silicate. Moreover, the enhancement of crystallization was obvious with the addition of clay loading, which functioned as a nucleating agent that could increase the rate of crystallization.

Processing, Properties, and Applications of Polymer Nanocomposites Based on Layer Silicates: A Review

The nanocomposites are materials, which involve fillers in the nanometer scale, yielding substantial improvements.Polymer-layered silicate nanocomposites have received much attention during the past decade and have great interest both in the academic field and in industry, since they often give more attractive improvement to material properties than both micro-and macrocomposite materials. This extensive review presents recent studies in polymer nanocomposites based on layered silicate. The background, morphology, preparations, and properties of these materials are discussed. The review covers and discusses various modern methods and equipments in the preparation of nanocomposites, deeply focusing on the morphology of nanocomposites and its effects on the overall properties. C Also, there were many successful nanocomposite preparations by the intercalation solution reported, for example, PEO/MMT nanocomposites, 66 polysulfone/OMLSdimethylacetamide, 171 PI/MMT-dodecylammonium, 220 and poly(vinyl alcohol)/Na + -MMT-water. 221

“…A quick indication and valuable information of the mechanical properties such as (hardness and elastic modulus) of different materials can be achieved by the nanoindentation test [38][39][40][41][42] . This technique is helpful and provides different properties by simple contact with the surface layers [43,44] .…”

The water absorption behavior, mechanical and thermal properties of vinyl ester matrix nanocomposites based on layered silicate were investigated. To characterize interlaminar structure of the nanocomposites, XRD, SEM, EDS, and TEM were performed. The mechanical and thermal properties of neat sample were improved by the incorporation of layered silicate. The improvement of the water repellence behavior was observed for the nanocomposites. The hardness and elastic moduli after water absorption was reduced due to the effect of water molecules entering into the polymer chains. However, the higher amount of clay reinforcement led to less reduction in hardness since the barrier properties.
