Nanocavitation in Self-Assembled Amphiphilic Block Copolymer-Modified Epoxy
Abstract
An amphiphilic block copolymer toughener was incorporated into a liquid epoxy resin formulation and self-assembled into well-dispersed nanometer scale spherical micelles with a size of about 15 nm. The nanosized block copolymer at 5 wt % loading can significantly improve the fracture toughness of cured epoxy thermosets without reduction in modulus at room temperature and with only a slight drop in glass transition temperature. The toughening mechanisms were investigated, and it was found that the 15 nm size block copolymer micelles could cavitate to induce matrix shear banding, which mainly accounted for the observed remarkable toughening effect. Other mechanisms, such as crack tip blunting, may also play a role in the toughening. A discussion of the possible reasons responsible for the observed attractive mechanical property improvements due to the block copolymer modification is given. Implications of the present finding for designing toughened polymers are also discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
