Abstract

Cellulose nanofibers (CNF) have been applied in various applications due to the abundant raw materials and excellent mechanical and thermal properties. In this work, CNF from Cigarette butts (CNF-CB) was used as emulsion stabilized for oil in water emulsion. CNF was prepared from regenerated cellulose fibers that were produced by deacetylation of Cigarette butts waste using autoclave and then hydrolysis by chemical treatment using sulfuric acid. The FTIR spectra of CNF-CB showed chemically convert from Cigarette butts waste, indicating removal of the acetyl group. TEM micrographs showed nanocellulose with diameters of 8-32.30 nm. XRD analysis shows that the CNF-CB is a cellulose II allomorph with a crystallinity index of about 88.04%. Thermogravimetric analysis showed high char residue for the nanocellulose compared to raw fibers. The addition of CNF-CB with a concentration of 0.5% into the oil-in-water emulsion (O/W) showed better stability than commercial surfactant. In conclusion, this approach offers a promising strategy for upcycling cigarette butts waste to produce nanocellulose, which could be used in various applications.
烟头再生纤维素纤维制备纳米纤维素纤维及其在酸洗乳剂中的应用
纤维素纳米纤维(CNF)由于其丰富的原料和优异的力学性能和热学性能而得到了广泛的应用。本研究以烟头CNF (CNF- cb)为乳化液稳定剂,对水乳液中的油进行稳定。以烟头废渣经高压灭菌法脱乙酰,再经硫酸化学水解制备再生纤维素纤维为原料制备CNF。CNF-CB的FTIR光谱显示了烟头废物的化学转化,表明乙酰基被去除。TEM显微图显示纳米纤维素的直径为8 ~ 32.30 nm。XRD分析表明,CNF-CB为纤维素II异形体,结晶度指数约为88.04%。热重分析表明,纳米纤维素的炭渣比原纤维高。在油水乳液(O/W)中加入0.5%浓度的CNF-CB,其稳定性优于工业表面活性剂。总之,这种方法提供了一种很有前途的策略,可以对烟头废物进行升级回收,以生产纳米纤维素,这种纤维素可以用于各种应用。
