Amino-functionalized multiwalled carbon nanotubes (MWCNT-NH 2 s) as nanofillers were incorporated into diglycidyl ether of bisphenol A (DGEBA) toughened with amine-terminated butadiene-acrylonitrile (ATBN). The curing kinetics, glasstransition temperature (T g ), thermal stability, mechanical properties, and morphology of DGEBA/ATBN/MWCNT-NH 2 nanocomposites were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis, a universal test machine, and scanning electron microscopy. DSC dynamic kinetic studies showed that the addition of MWCNT-NH 2 s accelerated the curing reaction of the ATBN-toughened epoxy resin. DSC results revealed that the T g of the rubber-toughened epoxy nanocomposites decreased nearly 10 C with 2 wt % MWCNT-NH 2 s. The thermogravimetric results show that the addition of MWCNT-NH 2 s enhanced the thermal stability of the ATBN-toughened epoxy resin. The tensile strength, flexural strength, and flexural modulus of the DGEBA/ATBN/MWCNT-NH 2 nanocomposites increased increasing MWCNT-NH 2 contents, whereas the addition of the MWCNT-NH 2 s slightly decreased the elongation at break of the rubber-toughened epoxy.

A dual-curable epoxyacrylate (EA) oligomer with one epoxide group and one vinyl group at each end was synthesized for the application as adhesive sealant in the liquid crystal display panels. However, after UV and thermal cure, the EA resin was brittle with a poor resistance to crack initiation and propagation. Liquid rubbers with different functional end groups were thus tried as toughening agents for the EA resin. Among all the rubber-toughened EAs, the EA-V5A5 added with vinyl-terminated and aminoterminated butadiene-acrylonitrile copolymers (VTBN and ATBN) each at 5 phr had the highest fracture toughness, tensile strength, and elongation at break but a lower initial modulus. To raise the modulus, submicron-sized silica particles (170 nm) with surface vinyl functional groups were further added to the EA-V5A5 to prepare the hybrid composites. Because of interfacial chemical bonding provided by the surface vinyl functional groups, both modulus and fracture toughness were increased by adding silica particles, without any appreciable decrease in extensibility. For the hybrid composite at 20 phr silica particles, the initial modulus, fracture toughness, and fracture energy were raised by 10.3, 100, and 267%, respectively, when compared to the neat epoxyacrylate. Owing to their strong interfacial bonding, the increase of fracture toughness was mainly due to the crack deflection and bifurcation on silica particles, in addition to the rubber particle bridging and tearing as evidenced by SEM pictures on the fracture surface.

Blends of poly(lactic acid) (PLA) and amine-terminated butadiene-acrylonitrile (ATBN) elastomer were prepared by solution with ATBN contents of 8-20 wt%. Films were molded by liquid deposition modeling 3D printing. Fourier transform infrared (FTIR) spectroscopy showed that the terminal carboxylic groups of the PLA chains reacted with the terminal amino groups of ATBN. Water was the byproduct of this reaction, causing PLA hydrolysis and accelerating the reaction. Thermogravimetric analysis (TGA) showed that components interaction caused a loss of PLA thermal stability. Scanning electron microscopy (SEM) of the blends revealed a porous morphology and no phase separation. There was change in the elongation when compared with neat PLA. Although the addition of a telechelic elastomer could improve PLA toughness, any benefits arising from such addition seem to be neutralized by PLA chain scission due to hydrolysis and porosity, resulting from the condensation reaction.
