Flame‐Retardancy Characterization of Polymer Nanocomposites

Smart composites — The new era in smart dentistry

“…42 The integration of different nanofillers to polymeric matrices has been shown to improve mechanical properties and opens up the possibility of creating new materials with a capacity to respond to different chemical, physical, or biological stimuli. 43 Different types of nanofillers have been used to obtain nanocomposites, which can be subdivided into two categories according to their ability to respond to stimuli:…”

Quantification of nanoparticles' concentration inside polymer films using lock-in thermography

“…The advent of nanotechnology has further pushed forward their design, leading to nanocomposites, which are built using nanomaterials. 2 Exploiting some of the unique properties of engineered nanoparticles (NPs) (such as superparamagnetism, 3 surface plasmon resonance, [4][5][6][7] quantum dots' optical properties, 8,9 and the exceptional mechanical resistance offered by carbon nanotubes 10 and graphene nanoakes 11,12 ), a series of novel materials have been prepared. 3,5,6,[8][9][10][11][13][14][15][16][17] This has led to the preparation of a plethora of sensors, [18][19][20] functional surfaces, [21][22][23] articial skins [24][25][26] and conducting polymer layers, [27][28][29][30] just to mention a few.…”

“…29,34 Traditional characterization methods, which rely on mechanical and optical properties of composites, are not always applicable, as they occasionally provide only indirect information about the composition and cannot always determine the spatial distribution of NPs. 2 Microscopy based techniques are powerful and can provide detailed information but are time consuming, at times destructive and require expensive tools, such as, e.g., energy dispersive X-ray spectroscopy (EDX) and focused ion beam (FIB). 35,36 Scattering techniques have also been used, but they are oen hard to interpret and heavily rely on complex mathematical models to extract information about NPs.…”

Compressive behaviour of nanoclay modified aerospace grade epoxy polymer

“…(i) to stiffen the matrix (increase the elastic modulus) without sacrificing the strain to failure (ii) to improve dimensional stability and thermal properties (iii) to enhance yield stress and strength (iv) to improve resistance to crack initiation and propagation (fracture toughness). [1][2][3][4][5][6][7] In order to achieve these property improvements, the selected nanofillers usually need to have a higher elastic modulus and a lower coefficient of thermal expansion than the matrix.…”

“…Several types of nanofillers are commercially available and commonly used for developing nanocomposites, [1][2][3][4][5][6][7][8][9][10][11][12][13][14] such as nanosilica, carbon nanotubes and montmorillonite organoclay, as shown in Fig. 1.…”
