Abstract
Superabsorbent Polymer (SAP) telah banyak digunakan dalam berbagai aplikasi. Walaupun demikian, bahan dasar dari SAP pada umumnya merupakan bahan sintetis yang berbahaya bagi lingkungan, salah satu polimer alami yang telah banyak digunakan untuk membuat SAP adalah Carboxymethyl Cellulose (CMC). Review ini membahas terkait agen crosslinker yang telah banyak digunakan untuk membuat SAP berbasis CMC, diantaranya adalah Citric Acid (CA), Epichlorohydrin (ECH), dan Polyethylene Glycol Diglycidyl Ether (PEGDE). Dari ketiga agen crosslinker tersebut telah dianalisis ikatan kimia yang terbentuk, morfologi, kemampuan penyerapan, degradasi. Citric Acid terbukti berhasil mengcrosslinkkan CMC, dengan struktur crosslink tersebut SAP yang diperoleh dapat menyerap air hingga 1200 kali, serta terdegradasi sebanyak 58% dalam waktu 24 jam. Dengan sifat-sifat tersebut, Citric acid telah mengungguli agen crosslinker lainnya dan menjadi agen crosslinker yang optimal untuk membuat SAP berbasis CMC.
============================================================
Superabsorbent Polymers (SAP) have been used in various applications. Despite that, the raw materials used to make SAPs are actually harmful to the environments. To counter that, a natural polymer such as Carboxymethyl Cellulose (CMC) was used to make SAPs. This review is centered around Crosslinking agents, one of the most important materials to make SAPs. Among all Crosslinking Agents, a few which are compatible with CMCs are Citric Acid (CA), Epichlorohydrin (ECH), dan Polyethylene Glycol Diglycidyl Ether (PEGDE). The testings used to compare the three Crosslinking Agents are chemical bonding, morphology, swelling capacity, and degradation. And from the three Crosslinking Agents, Citric Acid stand out as the more promising crosslinker. SAPs made of CA-crosslinked CMC can swell up to 1200 times of its dry weight, and it’s degradation rate is up to 58% in 24 hours. And so, with those properties in considerations, Citric Acid is the more promising Crosslinking Agent to make CMC-based SAPs.
