Synthesis, Characterization and Applications of Hair Nanofibres from Waste Human HairBy Uttam Kumar, C. R. Tripati, Ashok Kumar
Abstract: This research communication describes preparation of nano hair fibre from waste human hair. Human hair contains keratin protein in it, which enhances the tensile properties of hair and makes it stronger. Raw fibre of hair was washed with hot water and detergent to make it oil and dirt free and then treated with alkali, to make its surface rough which enhanced the bonding properties of fibre during reinforcement. The chemically …

Extraction and Characterization of Nanocellulose from Saw DustBy Uttam Kumar, Payal Sharma, Kanchan L. Singh, Ashok Kumar
Abstract: In this work, nanocellulose was extracted and fibrillated from wooden saw dust of Malaysian wood. The fibrillation of cellulose nanoparticles was done by two major steps such as chemical pre-treatment and acid hydrolysis. Firstly, the saw dust was pre-treated with alkali, and then de-waxing of saw dust was done. Then cellulose was extracted. Finally, it was chemically washed etc. The extracted chemically purified cellulose was further treated with acid hydrolysis …
