Polyanionic cellulose (PAC) hakika polymer ne, musamman abin da aka samu daga cellulose. Wannan fili mai ban sha'awa yana samun aikace-aikace masu yawa a cikin masana'antu daban-daban saboda musamman kaddarorinsa da ayyukansa.
Tsarin Cellulose na Polyanionic:
An samo polyanionic cellulose daga cellulose, wanda shine daya daga cikin mafi yawan polymers na halitta a duniya. Cellulose shine polysaccharide madaidaiciya wanda ya ƙunshi maimaita raka'a na glucose wanda aka haɗa tare da β(1→4) glycosidic bonds. Yana samar da tsarin tsarin farko na ganuwar tantanin halitta. Polyanionic cellulose an gyaggyarawa cellulose, inda wasu daga cikin rukunin hydroxyl na sarƙoƙin cellulose aka maye gurbinsu da ƙungiyoyin anionic. Waɗannan ƙungiyoyin anionic galibi sun haɗa da ƙungiyoyin carboxylate (-COO⁻), sulfonate (-SO₃⁻), ko ƙungiyoyin phosphate (-PO₄⁻). Gabatar da waɗannan ƙungiyoyin anionic suna ba da solubility na ruwa da sauran kyawawan kaddarorin ga polymer.
Haɗin gwiwar Cellulose na Polyanionic:
Polyanionic cellulose yawanci ana haɗa shi ta hanyar gyaran sinadarai na cellulose. Hanya ɗaya ta gama gari ta haɗa da amsa cellulose tare da fili na anhydride ƙarƙashin takamaiman yanayi don gabatar da ƙungiyoyin anionic akan kashin bayan cellulose. Yanayin amsawa da nau'in anhydride da aka yi amfani da su sun ƙayyade matakin maye gurbin (DS) na ƙungiyoyin anionic akan sarkar cellulose. Maɗaukakin ƙimar DS yana haifar da mafi girman narkewar ruwa da ingantaccen aiki a wasu aikace-aikace.
Abubuwan da ke cikin Cellulose Polyanionic:
Polyanionic cellulose yana nuna wasu kaddarorin na musamman waɗanda suka sa ya dace da aikace-aikace da yawa:
