Fig. 6: Mechanical reinforcement of polyethylene with CO₂ gas.

a Chemical structure of E–T. b Experimental and simulated SAXS patterns of E–T. SAXS patterns with and without CO₂ are shown as magenta and black plots, respectively. The Yarusso–Cooper model was used for the simulations³⁷. c Effects of CO₂ gas on Eʹ, Eʺ, and tanδ of E–T measured at 1 Hz and 25 °C. d Tensile behaviors of E–T measured at 26 °C ± 1 °C in N₂ and CO₂ gases. The strain rate was 0.09 s⁻¹.
