Multiple Structure Reconstruction by Dual Dynamic Crosslinking Strategy Inducing Self‐Reinforcing and Toughening the Polyurethane/Nanocellulose Elastomers

Advanced Functional Materials, 2023
High‐performance elastomers are expected to possess excellent healing and recycling ability, damage resistance in conjunction with high strength and toughness. Herein, a dual dynamic crosslinking strategy is implemented by multiple hydrogen and disulfide

Interfacial toughening with self-assembled monolayers enhances perovskite solar cell reliability

Science, 2021
Tougher solar cell interfaces The low formation energies of the active layers in perovskite solar cells lead to low-toughness materials that are compliant and soft, which limits their interface stability and long-term reliability. Dai et al.

Polyurethane Toughened Polylactide *

Polymer Bulletin, 1998
Brittle polylactide (PLA) was toughened by introducing 5 wt % of a poly(ɛ-caprolactone)(PCL) diol- and triol-based polyurethane (PU) network. The extent of cross-linking of the PU was varied by changing the ratio between diol and triol. The effects of the PU content and its crosslink density on the mechanical properties and the toughness of PU/PLA ...

Mechanisms of toughening in rubber toughened polymers

Acta Metallurgica, 1986
Abstract A method is presented whereby various potential contributions to the toughness of rubber toughened polymers can be quantified. The tendencies toward either synergism or additivity amongst mechanisms is emphasised for rubber stretching, cavitation and shear banding. The method reveals that specific experimental measurements of microstructural

Twin-Boundary Assisted Crack Tip Plasticity and Toughening in Lamellar γ-TiAl

Social Science Research Network, 2021
The internal twin-boundaries in lamellar γ-TiAl alloys, namely true-twin (TT), rotational boundary(RB), and pseudo-twin (PT), are known to be effective in strengthening the TiAl microstructures.

Commentary: Toughen up

BMJ, 2009
Most readers of the BMJ will, I’m sure, be stunned by the revelations in Karl Sabbagh’s article (doi:10.1136/bmj.a2066). A deluge of nearly 1000 hostile emails will strike most as the stuff of nightmares. The language of some of those missives—abusive and bigoted—will have seemed truly shocking.
