“…The hydrophobic EC backbones collapsed in water and formed the core of the micelles, and the hydrophilic PHEMA chains stayed at the shell of the micelles to stabilize the micelles (Mode-21, Scheme 8) [144]. EC-g-PAA showed various self-assembly behaviors in THF/water, according to the length and density of the branch chains [212]. The structure of the micelles was as same as that of EC-g-PHEMA in water.…”

“…Pada proses pengikatan silang, gugus OH and CH 2 OH mengalami reaksi kondensasi dengan melepaskan molekul air, menghasilkan jaringan tiga dimensi yang mengandung ikatan kovalen, karena itu ikatan β-1,4-glikosida relatif lebih tertutup hal ini menyebabkan matriks polimer terikat silang menjadi lebih tahan terhadap asam dan kerusakan selulosa dalam larutan asam merupakan reaksi hidrolisis ikatan β-1,4-glikosida, karena ikatan asetal tersebut tidak stabil dalam kondisi asam [15,16].…”

MODIFIKASI SELULOSA MENGGUNAKAN ASAM AKRILAT DAN TRIMETHALLYL ISOCIANURATE DENGAN METODE PRA IRADIASI PEROKSIDA. Modifikasi selulosa dengan asam akrilat menggunakan pengikat silang Trimethallyl Isocianurate (TMAIC) dengan teknik kopolimerisasi cangkok pra-iradiasi-peroksida telah berhasil dilakukan. Penelitian ini bertujuan untuk mendapatkan adsorben ion logam berbasis selulosa. Pengikat silang TMAIC digunakan untuk meningkatkan ketahanan asam dan termal dari selulosa-g-AA. Kondisi optimum reaksi pencangkokan diperoleh pada dosis radiasi 40 kGy, konsentrasi TMAIC 0,5 %(w/v), konsentrasi monomer 10 %(v/v), suhu pencangkokan 90°C dan waktu pencangkokan 6 jam, dengan persen pencangkokan rata-rata sebesar 42,37 %. Pengembangan dalam air turun sebesar 36 % setelah penambahan TMAIC. Hasil sintesis kopolimer selulosa-TMAIC-g-AA telah berhasil dikarakterisasi dengan FT-IR, TGA dan SEM. Selulosa terikat silang dapat digunakan sebagai adsorben ion logam Pb 2+ , dengan kapasitas adsorpsi sebesar 2,60 mg/g pada waktu kontak 2 jam dan pH 5 (konsentrasi awal Pb 2+ 10 mg/L). Isoterm adsorpsi yang sesuai dengan adsorpsi Pb(II) dengan kopolimer adalah isoterm adsorpsi Langmuir yang berarti energi adsorpsi konstan di semua sisi kopolimer tersebut.

“…Cellulose graft copolymers can self‐assemble into micelles in selected solvents. The morphology of the resultant micelles depends on the properties of both backbone and graft chains and on the properties of the solvents . Considering the properties of cellulosic backbone and graft chains, cellulose graft copolymers may have thermal‐, pH‐ or dual‐stimuli‐responsive properties, by which the cellulose graft copolymers can self‐assemble into micelles with different architectures.…”

In this review, recent progresses in the synthesis of new cellulose derivatives and graft copolymers are summarized. Cellulose derivatives synthesized in new cellulose solvents, such as ionic liquids and NaOH/urea, and the regioselective synthesis of cellulose derivatives have attracted increasing attention in recent years and could be a more active field for cellulose in the future. Cellulose graft copolymers with well‐defined architectures synthesized by controlled/living radical polymerizations such as atomic transfer radical polymerization and their stimuli‐induced assembly have been investigated extensively. Stimuli‐responsive functional materials can be fabricated using either cellulose derivatives or graft copolymers, and they can be used as biosensors and carriers for controlled delivery of drugs and genes. The fabrication of functional materials with cellulosic blocks and their applications have a bright future. © 2013 Society of Chemical Industry
