Kua whakawhanakehia e ngā kairangahau tētahi elastomer polyurethane hou e hangai ana ki tētahi whatunga urutau covalent hihiri i ahu mai i te waikawa ascorbic (A-CCANs). Mā te whakamahi i te pānga synergistic o te tautomerism keto-enol me ngā hononga carbamate hihiri, ka tutuki i te rauemi ngā āhuatanga tino pai: he pāmahana pirau wera o te 345 °C, he ahotea pakaru o te 0.88 GPa, he kaha pēhi o te 268.3 MPa (te mimiti pūngao o te 68.93 MJ·m⁻³), me te taumahatanga toenga i raro i te 0.02 i muri i te 20,000 huringa. Ka whakaatuhia hoki e ia te whakaora-ā-ia anō i roto i ngā hēkona me te whai huatanga hangarua tae atu ki te 90%, e tuku ana i tētahi otinga hou mō ngā tono i roto i ngā taputapu atamai me ngā rauemi hanganga.
Nā tēnei rangahau hou i hanga he whatunga urutau covalent hihiri (A-CCANs) mā te whakamahi i te waikawa ascorbic hei poraka hanga matua. Mā te tautomerism keto-enol i hangaia me ngā hononga carbamate hihiri, i hangaia he elastomer polyurethane whakamiharo. E whakaatu ana te rauemi i te ātete wera rite ki te polytetrafluoroethylene (PTFE) - me te pāmahana pirau wera tae atu ki te 345 °C - me te whakaatu i te taurite tino pai o te pakari me te ngāwari: he ahotea pakaru pono o te 0.88 GPa, me te kaha ki te pupuri i te ahotea o te 268.3 MPa i raro i te 99.9% te taumahatanga kōpeketanga me te mimiti i te 68.93 MJ·m⁻³ o te kaha. He mea whakamiharo ake, e whakaatu ana te rauemi i te taumahatanga toenga iti iho i te 0.02% i muri i te 20,000 huringa miihini, ka ora ake i roto i te hēkona kotahi, ā, ka tutuki te pai o te hangarua o te 90%. Ko tēnei rautaki hoahoa, e tutuki ai te whakataukī "he ika, he waewae pea hoki," e whakarato ana i tētahi otinga hou mō ngā tono pēnei i ngā taputapu mau atamai me ngā rauemi whakamarumaru rererangi, he mea nui te kaha ā-pūkaha me te roa o te taiao.
