“…Kuila et al reported epoxy/graphene oxide nanocomposites. The pure epoxy resin had very poor thermal conductivity, but the addition of 1% graphene oxide significantly enhanced the thermal conduction and the performance was similar to composite with 1% of single wall nanotubes.…”

Polymer/graphene based nanomaterials have attracted significant scientific interest in the recent years due to marked enhancement in the polymer properties at low filler fractions. The property enhancements are attributed commonly to high aspect ratio of graphene platelets, filler-polymer interactions at the interface, as well as uniform dispersion of the platelets in the polymer matrices. Graphene also provides opportunities to tune its surface in order to achieve compatibility with the polymer matrices. Occasionally, chemical binding of the polymer matrix to the graphene surface has also been achieved.

“…This in all probability is due to the fact that the improvement in the mechanical strength of a composite depends on effective stress transfer from polymer to nanofiller, whereas the thermal stability is guided by the chemical nature of the polymer, the type of filler and the modification route of the nanofiller. Earlier work in the literature also confirmed that the maximum improvements in mechanical and thermal properties are not proportionally related with respect to the filler loadings in the polymer matrix 8, 48–50…”

The homogeneous dispersion of nanofillers in polymer matrices to form polymer nanocomposites remains a challenge in the development of high-performance polymer materials for various applications. In the work reported, a stearate ionmodified Mg-Al layered double hydroxide (St-LDH) as nanofiller was incorporated in a silicone rubber (SR) matrix by solution intercalation and subsequently characterized. X-ray diffraction and transmission electron microscopy studies confirm the formation of a predominantly exfoliated dispersion of St-LDH layers of 75-100 nm in width and about 1-2 nm in thickness in the SR. Thermogravimetric analysis shows that the thermal degradation temperature of the exfoliated SR/St-LDH (1 wt%)nanocomposites is about 80 • C higher than that of pure SR. Differential scanning calorimetric studies indicate that the melting and crystallization temperatures are higher by 4 and 10 • C for 5 and 8 wt% St-LDH-loaded SR nanocomposites compared to neat SR. A significant improvement of 97% in tensile strength and 714% in storage modulus and a reduction of 82% in oxygen permeability have been achieved at 3 wt% St-LDH loading in SR.

“…Recently, polymer=layered double hydroxide (LDH) NCs have been studied extensively for their remarkable improvement in the mechanical properties, thermal stability, reduced gas permeability, and flame retardancy compared with virgin polymers and traditional organicinorganic composites [12][13][14][15][16][17] . This is mainly due to the effective dispersion of LDH layers of nanometer thickness with the aspect ratios of about 30-100 within the polymer matrix [18] .…”

Intercalated poly(amide-imide) (PAI)/modified layered double hydroxide (LDH) nanocomposites (NC)s were synthesized by the solution intercalation method. Modified LDH was synthesized from the co-precipitation reaction of the Al(NO 3 ) 3 Á 9H 2 O, Mg(NO 3 ) 2 Á 6H 2 O and N,N'-(pyromellitoyl)-bis-valine under ultrasound irradiation. An optically active amino acid containing PAI was synthesized by direct polymerization reaction of chiral diacid and 3,5-diamino-N-(thiazole-2-yl)benzamide under green condition. The synthesized materials were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), field emission scanning electron microscope (FE-SEM) and transmission electron microscopy (TEM) techniques. TEM and FE-SEM analysis confirmed that modified LDH was dispersed within the polymer matrix in intercalated and exfoliated forms.Keywords Layered double hydroxides; Nanocomposite; Poly(amide-imide); (S)-Valine amino acid; X-ray diffraction INTRODUCTIONInorganic=polymer nanocomposites (NCs) are a class of composites in which the inorganic phase dimensions are in the order of nanometers. These NCs contain only a few percent of well-dispersed inorganic components of nanometer size in an organic polymer, and exhibit better properties than pure polymers [1][2][3][4][5][6] . The most part of previous studied has been focused on NCs based on clay and layered silicates because the starting clay materials are easily available and their intercalation chemistry has been studied for a long time [7][8][9][10][11] .
