摘要： Bellows, for example, a roll bellows and a folding bellows, can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, using a mixture comprising at least one thermoplastic elastomer selected from the group of copolysters with a hard segment and a soft segment, wherein in a first step the at least one thermoplastic elastomer is mixed with approximately 0.8 wt. % to approximately 5 wt. % triallyl isocyanurate, based on the total amount of the mixture; in a second step the bellows is produced; and in a third step, the bellows is exposed to an ionizing irradiation in a range from approximately 140 kGy to approximately 350 kGy.

摘要： A method for preparing a biomass-based conductive hydrogel by 3D printing is provided. Firstly, a cellulose-based macromonomer, a rosin-based monomer, an acrylic acid monomer and an initiator are mixed in a certain proportion, stirred, and dissolved at 25-70° C. Then, diisocyanate in an amount of 5-10 wt % of a total mass of the monomers is added to the mixed solution and mixed uniformly to prepare a 3D printing photosensitive resin solution. An SLA light-curing 3D printer is used to print a hydrogel precursor 1 with a complex shape. Next, the hydrogel precursor 1 is heated to obtain a hydrogel precursor 2 with a dual-curing network. Finally, the obtained hydrogel precursor 2 is swelled in a 1-15 wt % alkaline solution at 5-60° C. for 0.1-10 hours to obtain the biomass-based conductive hydrogel.
