Iyi chete nhanho inodiwa kuvandudza iyo polyimide firimu

Kuita kwefirimu repolyimide kungavandudzwa sei? Ngatitarisei pamwe chete.

Polyimide firimu zvinhu imhando yekunyanya kupisa kupisa, corrosion resistance, mechanical properties, low dielectric properties, radiation resistance uye high processability, saka kushandiswa kwayo kwakafara zvikuru uye kwakakurumbira. Iyo ine zvakare yakakura kukosha kwekushandisa mundima yeaerospace.

Nekudaro, nekuda kwenzvimbo yakakosha muchadenga uye kusasimba kwepamusoro-tekinoroji yemagetsi zvikamu, static magetsi anokonzera kukuvadzwa kukuru kumidziyo yekubhururuka uye zvigadzirwa zvemagetsi. Iko conductivity yefirimu ye polyimide pachayo yakaderera zvakanyanya, iyo inoderedza kushandiswa kwayo mumhepo uye nzvimbo dzakasiyana-siyana mune zvakawanda, saka kuchinjwa kwe polyimide zvinhu kwakaunzwa pamberi.

Graphene yave iyo yekutariswa kwekutarisa pakarepo mushure mekugadzirwa kwayo muna 2004, uye yakanakisa magetsi conductivity, kupisa kwemafuta uye michina zvimiro zvese zviri muzvikamu zvekuita. Kuwedzera graphene kune zvinyorwa kunovandudza conductivity yayo uye kugadzikana kwekupisa.

Kumwe kugadziridzwa kwesimbi dopant doped mune polymer inoumbwa zvinhu inoda kuitiswa pane yakanyanya tembiricha. Iyo yakanyanya tembiricha kuramba ye polyimide inogona kuve nechokwadi chekuora kwakajairika uye shanduko yesimbi dopant. Iyo yakawanda synthesis nzira dze polyimide inobvumira kuti doping nzira dzisiyane. Pamusoro pezvo, iyo yakakwira solubility ye polyamic acid kune yakasimba polar zvinonyungudutsa zvinogona kubatsira inorganic zvinhu kuve zvirinani doped mu polyimide firimu.

Nokudaro, mubepa rino, graphene inobatanidzwa mu polyimide kuti igadzirise iyo polyimide firimu kuti ivandudze zvikamu zvose zvekushanda kwefirimu yepolyimide. Chekutanga kutariswa kana graphene ichibatanidzwa mune polyimide zvinhu ndiko dispersibility. Muchokwadi, kupararira kwezvinhu zvemukati mune inorganic/polymer zvinhu kwakakosha zvakanyanya, uye kufanana kwekupararira kunogona kukanganisa firimu rakagadzirwa rakaumbwa. Performance.

Ichi chinyorwa chakatanga kudzidza nzira ye graphene incorporation, kutarisira nzira iri nani yekusanganisa, uye kuedza uye kuratidza kushanda kwefirimu inosanganiswa. Zvinotarisirwa kuti kuwedzerwa kwegraphene kuchakanganisa conductivity uye kupisa kwezvinhu zvepolyimide firimu. Uye zvimwe zvinhu zvine chokwadi
