• the control of mechanical properties by polymer design has been a significant area of interest, mechanochemistry of polymers and related molecules has recently emerged as a field of growing scientific and industrial interests [270][271][272][273]. The development of mechanochromic polymers, which

Among them, hydrothermal methods based on ammonium-releasing reagents (ARRs), commonly urea or hexamethylenetetramine, are especially interesting since they allow one to obtain large and highly crystalline

Keywords: mechanochemistry; polyurethane; porous carbon; supercapacitor; waste; Introduction Currently more than 275 million tons of plastics end up as waste every year, 12.7 million tons of which accumulate in the oceans [1][2]. This waste is mainly packaging materials such as

• in a solvent-free manner [50][51][52]. Mechanochemistry is an innovative synthesis concept that can be conducted without solvents. It is cost-efficient and sustainable at the same time [53]. Mechanochemistry is well established in the field of pharmaceutical [54][55], organic [56][57][58], and

• inorganic chemistry [59][60][61][62]. Mechanochemical reactions are initiated and controlled by mechanical energy, for example provided by the collisions of milling balls in high-energy ball mills. The advantages of mechanochemistry are obvious. Syntheses can be conducted without solvents [63][64], and
