In this study, mechanical, thermal, and morphological properties of the nanocomposites fabricated with the optimized blend of poly(ether ether ketone) (PEEK) and poly(ether sulfone) (PES) incorporated with nanobarium titanate (BT) were investigated. The optimized blend was based on the mechanical and thermal properties of the PEEK and PES in the ratio of 75 : 25 wt %. Nanoparticles were incorporated into the optimized blend with the help of twin‐screw extruder. The concentration of nano‐BT was varied from 2 to 6 wt % (0.41–1.28 vol %). With the increase in the nanosized BT concentrations, the tensile strength, tensile modulus, and elongation at break increased, whereas the crystallinity of the nanocomposites calculated by using differential scanning calorimetry method was found to decrease marginally. Morphological studies were carried out using scanning electron microscopy. The nanocomposites were evaluated by using theoretical predictive models according to “Pukanszky model” applicable to tensile strength and “Takayanagi's model” and “Guth and Smallwood model” applicable to tensile modulus. Upper and lower boundary of Hashin–Shtrikman model as well as Paul's model, applicable to tensile modulus, were also used to compare the experimental data. © 2012 Wiley Periodicals, Inc.

“…The blend of PEEK/PEK [Figure 5(a)] exhibits a homogeneous structure and also indicating miscibility of the blend system. The miscibility of PEEK/ PEK blend, we have already published in our previous paper [41]. The SEM image of PEEK/PEK blend is indicating homogeneous structure free of any separated domains at the obtainable resolution of SEM.…”

In the present study, two different blends were used as matrix. One of the blends is consisting of the two semi-crystalline polymeric components. The other blend is the combination of one semi-crystalline polymer and one amorphous polymer. The semi-crystalline poly (ether ketone) (PEEK) is the common component in both the blends. The other polymers are poly (ether ketone) (PEK) which is semi-crystalline and poly (ether sulphone) (PES) which is amorphous in nature. The blends were optimized based on their thermal and mechanical properties. Twin screw extrusion technique was used for the incorporation of nanoparticles of barium titanate (BT). The nano filler of BT was varied from 2 to 6wt% (0.41 to 1.28 vol%). The fabricated nanocomposites were tested for tensile properties such as tensile strength, tensile modulus and elongation at break. 'Pukanszky model' related to tensile strength was used to evaluate the reliability of the tensile data of the fabricated polymer nanocomposites obtained from the experimental results. From 'Pukanszky model', it was observed that tensile strength seemed to govern by the adhesion parameter, B σ , which correlates the interphase and the interfacial interaction.

“…In consequence of this, the nanocomposites in which heterogeneous nucleation takes place and interfacial adhesion varies, such a deviation between 'rule of mixture' and 'experimental results' is observed. 41,42 The limitations of the different models used to compare the experimental results and theoretical value of the tensile modulus of filled system are discussed here. The tensile modulus as well as strength, in general, of carbon nanotube reinforced polymer nanocomposites are found to increase with CNTs loading, alignment, distribution and dispersion in the matrix.…”

“…In consequence of this, the nanocomposites in which heterogeneous nucleation takes place and interfacial adhesion varies, such a deviation between 'rule of mixture' and 'experimental results' is expected. 41,42 The predictive model proposed by Pukanszky et al 36 was used to study the tensile strength data of the nanocomposites in order to assess the level of interfacial interaction. The values of B σ are listed in Table 2.…”

In this article, we have studied the effect of carbonaceous nanofillers viz. fullerenol (0D), carboxylated multi-wall carbon nanotube (MWCNT, 1D), hydroxylated graphene (2D) and combination of carboxylated CNT and hydroxylated graphene as 3D in thermoplastic polyurethane on the tensile properties of the fabricated cellular structures. The concentration of nano-fillers was varied as 0.1, 1, and 5 wt%. Tensile properties of the nanocomposite cellular structures were measured as per ASTM D882 at 20 C (below glass transition temperature, T g) and 40 C (above T g). The results have shown that the tensile strength was found to increase by 200%-300% and the tensile modulus was found to increase by 150%-300% for 2D and 3D nano-fillers while significantly poor results were observed for 0D. However, the test data tensile strength and modulus showed marginal increase at 20 C and marginally low at 40 C for 1D filler. The interfacial adhesion was calculated by using experimental tensile data and the predictive models. The interfacial adhesion parameter (B σ) calculated using Pukanszky equation was found significantly higher value for 2D (B σ20 = 195.8) and 3D (B σ20 = 192.0) fillers while poor adhesion was observed for 0D (B σ20 = −81.6) fillers. The developed cellular structured materials were also evaluated by attenuated total reflection Fourier transform IR spectra, differential scanning calorimetry, X-ray diffraction, scanning electron microscope, and transmission electron microscope.

They have high energy shock absorption capacity, acoustic and thermal insulating properties, filtering applications, 2 and so forth. They are also widely used in automobile, aircraft industry, buildings and packaging. 2 The foams of PUs are used as insulating and core materials for cooling, furniture, and freezing systems, shipbuilding, in house building, 3 and so forth.
