Polyacrylonitrile 丨 CAST 25014-41-9

Polyacrylonitrile (CAS, CAS 25014 -}}}}}}}}}}}} {{{}} Its dominant application is as the precursor for carbon fibers - PAN-based precursors are thermally stabilized and carbonized to produce high-strength, high-modulus fibers used in aerospace, automotive, sporting goods, and wind-turbine composites. Hauv textiles, pan fibers (feem ntau yog siv acrylics) yog siv rau cov hws, cov ntaub pua plag thiab felts-zoo li tes, xim zoo nkauj thiab huab cua tsis kam. Yias yog dav siv los ua ultrafiltration thiab microfiltration membranes thiab Electrospan Nanofibers rau dej kho, roj sib cais, thiab biomedical scaffolds. Nws kuj tseem pom hauv cov txheej txheem tshwj xeeb, cov nplaum, thiab cov khoom pib rau ion-pauv cov resins thiab ua kom haum carbons (tom qab lub ntsej muag ua kom zoo dua qub Thaum kawg, Yias Copolymers thiab sib xyaw ua haujlwm tau ua haujlwm rau kev ua suab thiab tshuaj lom neeg rau cov ntawv thov kev lag luam rau cov khoom siv rau Niche.

Lub lauj kaub cov nqi los ntawm nws cov khoom siv tshuaj lom neeg (cov pab pawg nitrile) thiab cov khoom siv uas ua raws. Lub Nitrile Moamety muab cov kev sib txuas lus muaj zog uas muaj zog tensile muaj zog, thiab cov kuab tshuaj lom zem piv nrog ntau cov khoom lag luam polymers. Vim tias lub lauj kaub carbon ntau ua ntej, nws yog cov preferor prefly rau kev hloov pauv rau cov carbon fiber nrog cov tensile modulus zoo nkauj thiab qaug zog. Yias fibers yog lub teeb yuag, huab cua tiv taus, thiab yooj yim ua kom zoo nkauj- ua rau cov textiles thiab sab nraum zoov. Rau cov kua mis thiab hluav taws xob khoom, lauj kaub lub incality (solubility nyob rau hauv cov qauv Polrvently, kev ua haujlwm yooj yim (hydrophilization, grafting, crosslinking). Hauv cov txheej txheej thiab cov adsorbents, pan {{6} Cov ntaub ntawv muab cov khoom siv hluav taws xob muaj peev xwm xa cov khoom siv thermal ruaj khov thiab lub taub hau. Zuag qhia tag nrho, Yias ua ke txhua yam ua ke ruaj khov, thermal / tshuaj kho zog, thiab ntau yam kev siv dav dav.
