“…The CTEs of the ZrW 2 O 8 and Zr 2 WP 2 O 12 in this study were in good agreement with previous experimental results. 1,2,18,22,23 The CTEs of the composites were negative and increased with the Zr 2 WP 2 O 12 content. When the Zr 2 WP 2 O 12 volume fraction in the composites was increased from 0 to 75 vol%, the CTEs of the composites increased from −9.1 × 10 −6 to −3.1 × 10 −6 K −1 and from −5.0 × 10 −6 to −1.9 × 10 −6 K −1 over 323-373 and 473-673 K, respectively.…”

“…However, in some cases, such as Al 2 TiO 5 , microstructural design and microcrack formation can be used to advantage to produce low thermal expansion materials with high thermal shock resistance [10]. On the other hand, the second approach makes use of the addition of thermomiotics, as the dispersed phase, in composites [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The most common role of thermomiotics in composites is to control the CTE of the matrix phase, which could be a metal, ceramic or polymer.…”

“…This NTE material has been used for the reduction of CTE of polyimide, polyester and epoxy resin [11, 15-17, 23, 24], while, as far as the authors are aware, there are no reports on its use in a PE matrix. On the other hand, the thermomiotics and low CTE compounds from the A 2 M 3 O 12 family are rarely cited in the literature as the dispersed phases for controlling CTE in composites [14,18,19,22,40]. An advantage of the compounds from this family is their wide chemical flexibility, resulting in a variety of orthorhombic phases with CTEs ranging between -11 9 10 -6 and 2 9 10 -6 K -1 [8,41,42].…”

“…It is also significant that some of the A 2 M 3 O 12 compounds are routinely synthesized from inexpensive reagents, which is not the case for ZrW 2 O 8 and related compounds. There are currently just a few reports of the application of A 2 M 3 O 12 compounds as fillers in ceramic-ceramic (MoO 3 , ZrO 2 , ZrSiO 4 and ZrW 2 O 8 featuring as matrices) [14,19,22,40] and ceramic-metal (Mg and Cu matrices) [18,40] [9].…”

Al2Mo3O12/polyethylene composites with reduced coefficient of thermal expansion

Recently, polymer composites reinforced with low fractions of thermomiotic nanoceramics have triggered a lot of research. The efforts have been focused on achieving considerable reduction of the coefficient of thermal expansion (CTE) of polymeric materials without deterioration of other physical properties. In this context, polyethylene (PE) composites reinforced with different loads of Al 2 Mo 3 O 12 nanofillers (0.5-4 mass %) were fabricated by micro-compounding. To enhance the interfacial interaction between the two components, chemical functionalization of Al 2 Mo 3 O 12 was performed with vinyltrimethoxysilane (VTMS) prior to micro-compounding. Infrared spectroscopy and thermogravimetry demonstrated the successful grafting of VTMS on the Al 2 Mo 3 O 12 surface. The composites showed strongly decreased CTEs, up to 46 % reduction for loadings of 4 mass % compared with neat PE, suggesting intimate filler-matrix interactions. The variation of CTEs of the composites in terms of the filler fraction was successfully described by Turner's model allowing calculation of the bulk modulus of monoclinic Al 2 Mo 3 O 12 (13.6 ± 2.6 GPa), in agreement with the value obtained by an ultrasonic method. The thermal stability of the composites was improved, although the addition of functionalized fillers decreased the degree of crystallinity of the PE to a small extent. The Young's modulus and yield strength of the composites increased from 6.6 to 19.1 % and 4.0-6.0 %, respectively, supporting the existence of strong filler-matrix interactions, contributing to an efficient load transfer.

“…In the last decade, many studies have investigated negative-CTE ceramics to reinforce MMCs with a low CTE and high TC, such as β-eucryptite (AlLiSiO 4 )14151617 and ZrW 2 O 8 181920. However, the CTE of β-eucryptite (approximately −0.7 × 10 −6 K −1 ) is not as low as expected and microcracks are easily formed in the bulk β-eucryptite ceramics due to its poor strength.…”

The properties of metal matrix composites (MMCs) can be optimized effectively through adjusting the type or the volume fraction of reinforcement. Generally, the coefficient of thermal expansion (CTE) of MMCs can be reduced by increasing the volume fraction of the reinforcement with lower CTE than metal matrix. However, it is great challenge to fabricate low CTE MMCs with low reinforcement volume fraction because of the limitation of reinforcement CTEs. SrxBa1−xTiO3 (SBT) powder presents negative thermal expansion behavior during the phase transformation from tetragonal to cubic phase. Here, we demonstrate that the phase transformation of SBT can be utilized to reduce and design the thermal expansion properties of SBT particle-reinforced Cu (SBT/Cu) composite, and ultralow CTE can be obtained in SBT/Cu composite. The X-ray diffraction analysis on heating indicates that the temperature range of phase transformation is extended greatly, therefore, the low CTE can be achieved within wide temperature range. Landau-Devonshire theory study on the phase transformation behaviors of SBT particles in the composite indicates that thermal mismatch stress significantly affects the Curie temperature of SBT particles and the CTE of the composite. The results given in the present study provide a new approach to design the MMCs with low CTE.
