Ukuhambelana ne-Adipic Dihydrazide (ADH)

Ukudibanisa kwe-DAAM kunye ne-ADH isetyenziswa ngokubanzi kwiinkqubo ze-polymer ezidibeneyo. Ukusabela phakathi kweqela le-ketone le-DAAM kunye neqela le-hydrazide kwi-ADH liphumela kwikhonkco elihlala ixesha elide le-hydrazone, eyenza:

  • Ukomelezwa kwamandla oomatshini.
  • Ukumelana okuphezulu kwe-thermal.
  • Ukuguquguquka okulungiselelwe ngokuxhomekeke kwiimfuno zokuqulunqwa.

Indlela yokusabela:

  1. Ukusebenzisana kweKetone-Hydrazide:I-DAAM + ADH → i-Hydrazone Bond
