PREPARATION AND CHARACTERIZATION OF OXIDIZED NANOCELLULOSE: STRUCTURAL AND RHEOLOGICAL PROPERTIES

Fayruza M. Urishova, Makhliyo M. Kuzieva, Dilnavoz G. Batirova, Abdumutolib A. Atakhanov, Nurbek Sh. Ashurov, Dmitriy I. Shiman


The use of potassium permanganate (KMnO₄) as an oxidizing agent provides a relatively straightforward yet effective route for tailoring the structure of cellulose under acidic conditions. In this work, microcrystalline cellulose (MСС) was subjected to KMnO₄ oxidation to obtain ... Read More

OPTIMIZATION OF THE SYNTHESIS OF SULFUR CELLULOSE COMPOSITES BY INVERSE VULCANIZATION: INFLUENCE OF TEMPERATURE, TIME, AND COMPONENT RATIO

Saydullo Kh. Azimov, Umida R. Baltayeva, Umida Kh. Asranova


This article presents the optimization of sulfur-cellulose composite (SCC) synthesis via inverse vulcanization using waste elemental sulfur (S_8) and activated cotton husk. A three‑factor Box-Behnken design was applied (factors: temperature 160-190°C, time 90-180 min, S:Org mass ratio 40:60-60:40). Regression models ... Read More
