In Situ Deformation

Deformation behavior of nanocomposites based on an ethylene/1-octene copolymerand multiwalled carbon nanotube (CNT) was investigated by means of an atomic forcemicroscope (AFM). Via a special tensile module integrated to an optical microscope, it waspossible to record the stress-strain diagrams of the composites using miniaturized tensilespecimens. By analyzing strain induced structural changes occurring at differentsuccessively applied loads, it was possible to correlate the deformation mechanismsoccurring on various length scales (i.e. at macroscopic, microscopic as well as nanoscopiclevels) to different degrees of deformation. It was noteworthy that, contrasting theproperties of other nanocomposites described so far in the literature, both the strength andtoughness of the composites were found to enhance. It was found that the deformation of thecomposite on nanoscopic scale was inhomogeneous owing to anisotropic properties of theCNTs and their alignments. After unloading the sample, the nanostructure of the originalmaterial was fully regenerated explaining the macroscopically observed elastomericproperties.Keywords: Ethylene/1-octene copolymer; CNT; Deformation mechanism; AFM; In situ deformation testsDOI: 10.3126/jncs.v26i0.3626Journal of Nepal Chemical SocietyVol. 26, 2010Page: 22-30

Silicone Emulsion

Polymer composites with a high electrical conductivity ( σ) to thermal conductivity ( k) ratio have been intensively investigated in recent years. While highly conductive materials, such as metallic fillers or conducting polymers, were used to enhance σ, microstructural engineering was used to decrease k by forming porous structures, such as aerogels or 3D networks. These structures, however, were mechanically vulnerable and could only have limited applications. In this study, multiwalled carbon nanotube /silicone composites with a high σ/k ratio were developed by forming a double-segregated multiwalled carbon nanotube network in the porous body of the composites. The unique microstructure of the composites was created by a novel fabrication process: layer-by-layer deposition with in-situ polymerization of silicone emulsion particles dispersed in a water solvent. This novel process yielded very thick films, >200 µm, with high σ/k values, ∼2 × 104 (S/m)/(W/m·K). These high σ/k composites can be used for various applications, such as resistive heating elements, thermoelectric materials, and wearable thermotherapy.
