“…Then, the peak intensity of the O-H group increased after alkali treatment, bleaching, and hydrolysis, which indicated an increased cellulose content. The peak at 2922 cm −1 was related to the stretching vibration of the C-H produced by the methyl, and methyl groups, in cellulose, hemicellulose, and lignin [ 28 ]. The peak at 898 cm −1 corresponds to the –CH 2 of glycosidic β in cellulose [ 20 ].…”

The purpose of this study was to utilize cellulose from tea waste as nanocrystalline cellulose (NCC), which is used as a filler in poly(vinyl) alcohol (PVA) nanocomposites. To obtain the NCC, a chemical process was conducted in the form of alkali treatment, followed by bleaching and hydrolysis. Nanocomposites were formed by mixing PVA with various NCC suspensions. With chemical treatment, lignin and hemicellulose can be removed from the tea waste to obtain NCC. This can be seen in the functional groups of cellulose and the increase in crystallinity. The NCC had a mean diameter of 6.99 ± 0.50 nm. Furthermore, the addition of NCC to the PVA nanocomposite influenced the properties of the nanocomposites. This can be seen in the general increase in opacity value, thermal and mechanical properties, and crystallinity, as well as the decrease in the value of the swelling ratio after adding NCC. This study has revealed that NCC from tea waste can be used to improve the physicochemical properties of PVA film.

“…Sulfonated cellulose is a potential immunosorbent material (Rocha et al 2018) and green flocculation agent for mineral particles (Liimatainen et al 2013). Sulfonated cellulose film has a potential application as a separator membrane in lithium-ion batteries (Thiangtham et al 2019). The purpose of this study was to extract sulfonated nanocrystals (SCNCs) via the sulfonation of DAC.…”

“…Pan and Ragauskas (2014) produced CNFs with a width of 15 nm to 45 nm and length of 1 μm following the same procedure. Thiangtham et al (2019) obtained transparent sulfonated suspensions via the sulfonation of DAC and found the suspensions contained cellulose particles, but unfortunately there was no further exploration of these particles.…”

Microcrystalline cellulose was oxidized via periodate followed by sulfonation. The sulfonated cellulose nanocrystals were obtained through centrifugation, dialysis, and sonication. The sulfonated cellulose nanocrystals were rod-like and had an average length of 140 nm to 153 nm and an average width of 8 to 10 nm. The Fourier transform infrared profiles and polyelectrate titration demonstrated successful introduction of the sulfonated groups into the cellulose nanocrystals. The sulfonated cellulose nanocrystals had a higher crystallinity index than dialdehyde cellulose. The thin films fabricated via the casting of the sulfonated cellulose nanocrystals suspensions were highly hydrophilic.

Penelitian ini bertujuan untuk mengadsorpsi zat pewarna sintetis metilen blue menggunakan Mikrocrystallincellulose (MCC) Tterimobilisasi nanopartikel cupri oxide/periodat (MCC/CuO-NP/KIO4) berbasis tongkol jagung dengan aktivasi NaOH 14%. Hasil karakterisasi MCC: Viscositas 86 cp, Selulosa 88.4%, Alfa-selulosa 45.2%. Adsorben (MCC/CuO-NP/KIO4) yang dihasilkan dikarakterisasi menggunakan FT-IR, SEM, XRD. Karakteristik spektra FT-IR (MCC/CuO-NP/KIO4) menunjukkan adanya puncak C=O yang sangat tajam pada 1055.70 cm-1dan 1028.37 cm-1 berasal dari getaran C-O-C. Indikasi adanya puncak partikel CuO pada bilangan gelombang 894.62 cm-1 , 1158.19 cm-1 , 1314.17 cm-1 . Difraktometer sinar-X (XRD) menunjukkan terjadinya penurunan kristalinitas serat sebagai hasil dari oksidasi. Permukaan morfologis selama oksidasi diamati menggunakan SEM. Pengukuran kapasitas adsorpsi metilen blue menggunakan Spektrofotometer UV-VIS. Pembuatan kurva standar dengan konsentrasi larutan standar (1 ppm, 5 ppm, 10 ppm, 15 ppm, 20 ppm) menghasilkan nilai r = 0.9888. Kapasitas adsorpsi yang dihasilkan dengan variasi konsentrasi larutan metilen blue 1ppm, 3 ppm, 7 ppm, 9 ppm adalah 70% - 80%.
