In the present work a recyclable and reprocessable vitrimer suitable for pultrusion process has been formulated pultruded profile reshaped by thermoforming manufactured therefrom. A DGEBA epoxy resin with medium range viscosity bis(a-aminophenyl disulfide) as dynamic crosslinker were used synthesis of vitrimer. The thermal stability was studied thermogravimetric analysis (TGA) curing behaviour kinetics means scanning calorimeter (DSC) rheology measurements. Mechanical properties resins its...
Abstract Novel nanocomposites prepared by melt mixing of MWCNTs in a hot‐melt adhesive PCL‐based polyurethane are investigated. The nucleating effect and the confinement they cause to polymer chains considered. broadening glass transition is indicative growth immobilized amorphous fraction adhered MWCNTs. In molten state formation combined polymer/MWCNT network observed. Practical requisites hot adhesives, such as adequate melting temperature, crystallization degree, viscosity preserved when...
Abstract On the basis of an analysis results presented in literature, currently existing knowledge about relationships between microstructural and physical properties hard coatings is discussed. Particular emphasis placed on role features, such as grain boundaries, nonequilibrium structures, impurities, texture, controlling film hardness. electrically conductive adhesives (ECAs) focus obtained with ECAs that contain carbon nanotubes (CNTs) fillers. The review divided curable based epoxy...
We investigated polyurethane (PU)–carbon nanotube (CNT) nanocomposites (PU/CNT) in a range of concentrations from 1 to 8 wt% CNT as hot melt adhesives. studied the thermal properties nanocomposites, which is relevant an applied point view. The phase angle plots versus complex modulus results revealed existence maximum above given concentration. intensity peak and associated relaxation time was analyzed with percolation theory, leading new method determine rheological threshold. A lower...
The properties of multiwall carbon nanotubes (MWCNT)/polyurethane (PUR) nanocomposites after being submitted to flow, i.e., in conditions similar their application as electrically conductive adhesives (ECA), are investigated. A decrease the elastic modulus is observed flow stopped, compatible with a rearrangement MWCNT/PUR network during flow. implications viscoelastic results on probe-tack data elucidated and slightly higher energy adhesion for sheared samples. Dynamic measurements reveal...
