9,9-Bis (3,4-dicarboxyphenyl) fluorene Dianhydride / BPAF cas: 135876-30-1

Ibisobanuro bigufi:

9,9-bis (3,4-dicarboxyphenyl) fluorene dioic anhydride, bakunze kwita BDFA, ni imiti ivangwa na molekile ya C32H14O6.Hamwe n'uburemere bwa molekile ya 494.45 g / mol, iyi nteruro irangwa no guhagarara kwayo kudasanzwe, aho gushonga cyane, hamwe no gukomera kwinshi mumashanyarazi atandukanye.

Ibicuruzwa

BDFA ikoreshwa cyane nkigice cyingenzi muguhuza imikorere yimikorere ya polymers nibikoresho.Imiterere yihariye ya molekile, igizwe nimpeta ebyiri za benzene zifatanije numugongo wa fluore, zitanga ibintu bidasanzwe byubushyuhe nubukanishi kuri polymers zavuyemo.

Ubushyuhe budasanzwe bwubushyuhe bwa BDFA bushingiye kuri polymers bubafasha guhangana nubushyuhe bwo hejuru, bigatuma bukoreshwa mubikorwa byindege, ibinyabiziga, na electronics.Izi polimeri zigaragaza imbaraga zidasanzwe zo guhangana nubushyuhe, imirasire ya UV, hamwe na ruswa yangiza imiti, bigatuma kuramba no kuramba mubidukikije bisaba.

Byongeye kandi, BDFA ishingiye kuri polymers ifite ibikoresho byiza byo gukwirakwiza amashanyarazi, bigatuma ihitamo neza kubikoresho byamashanyarazi na elegitoroniki.Izi polymers zirashobora gukoreshwa mugukora insulator, ibikoresho bya elegitoronike, hamwe nimbaho zicapye zicapye, aho amashanyarazi agomba kugabanywa.

BDFA nayo izwiho ubushobozi bwo kuzamura imbaraga za mashini no gukomera kwa polymers.Mugushira BDFA mumibare ya polymer, ibikoresho bivamo byerekana imbaraga zingirakamaro, kurwanya ingaruka, hamwe no guhagarara neza.Ibi bituma bakenerwa mubikorwa byubwubatsi, ibinyabiziga, nibicuruzwa byabaguzi.

Usibye kuba ikoreshwa muri polymers ikora cyane, BDFA isanga ingirakamaro mugukora imiti yihariye, amarangi, hamwe na pigment.Imiterere yihariye ya molekulari itanga amahirwe yo kwihindura, yemerera abashakashatsi nababikora gukora ibikoresho bishya bifite imiterere yihariye.
