“…Thus, high-value utilization of throwaway waste material is of great importance for the sustainable development of the society. [5][6][7][8][9][10] Chewed gum features flexibility, viscosity, and biocompatibility, which promise great potential in stretchable and flexible electronics. 11 For instance, an elastic, attachable, and costefficient chewing-gum-based sensor fabricated by introducing aligned carbon nanotubes (CNTs) into chewing gum through multiple stretching and folding steps could sense strain up to 530% with high sensitivity and durability, thus demonstrating capability for monitoring body movements and tracing slow breathing efficiently.…”

Recycling of waste wind turbine blades for high‐performance polypropylene composites

“…To dissipate the heat generated during the milling procedure, circulating ethylene glycol was used as a coolant. Further operational details are available in our prior publications 29–31 …”

“…Further operational details are available in our prior publications. [29][30][31] The WFRE powder was immersed in a 2 wt.% coupling agent solution (the coupling agent solution consisted of a mixture of ethanol and water in a mass ratio of 4:1. The powder mass was 40% of the solution mass) and stirring with a mixing rod at a speed of 500 rpm for 30 min, subsequently dried.…”

Graphene stripping, a convenient and environmentally friendly technology for the preparation of polyurethane/graphene nanocomposites as a new type of highly wear‐resistant materials

“…Among mechanical milling techniques, solid-state shear milling (S 3 M) technology has the advantages of wide applicability, convenient operation, high efficiency, simplicity, energy saving, and no pollution 24 and can be used for grinding, mixing, and hydrochemical reactions of polymers and fillers. 25,26 At present, this technology has been widely used in polymer microgrinding preparation, Lai et al 27 used S 3 M technology to achieve rubber decrosslinking and recycling, furthermore, the reclaimed products via thermoplastic re-processing had excellent mechanical properties, and the optimal stress and strain were increased by 208.2% and 269.4%, respectively, compared with the products made from virgin scraps, this is a great progress. Zhang et al 28 used S 3 M technology to improve the crystallinity, thermal and mechanical properties of PVDF/graphene composites, realizing the exfoliation of graphene as well as the solid grafting of graphene layers on PVDF molecules, improving the dispersion of graphene layers in PVDF and making them effectively exert their heterogeneous nucleation as well as enhancement effects on PVDF.…”
