The applicability of cotton-bleached soda pulp (C-BSP) was investigated as a raw material for manufacturing cationic nano-fibrillated cellulose (NFC) via quaternization of anionic NFC using glycidyl-trimethyl-ammonium chloride (GMA). The anionic NFC was prepared by beating and micro-grinding C-BSP, and quaternization was performed post treatment to induce a charge reversal in anionic NFC. The characteristics of cationic NFC manufactured using C-BSP and hardwood-bleached kraft pulp (Hw-BKP) as a control were analyzed. Relatively higher mechanical energy was required to prepare anionic NFC from C-BSP than that from Hw-BKP. Fourier transform infrared and zeta potential analyses results showed that quaternization by GMA post treatment electrostatically induced charge reversal in anionic NFC. However, GMA did not affect the fiber width and viscosity of the cationic NFCs. It was found that cationic NFC could be manufactured via quaternization of anionic NFC manufactured from C-BSP using less GMA than that for Hw-BKP.

“…Multiple acids, notably sulfuric acid (H2SO4) and hydrochloric acid (HCl), have been exploited for this purpose. The outcome of cellulose hydrolysis, whether it results in cellulose nanocrystals (CNCs) or cellulose nanofibrils (CNFs), depends on the particular type of acid employed Cellulose nanocrystals (CNCs), known for their high aspect ratios and superior dispersibility in solutions of water, are often created through the utilisation of sulfuric acid [17,18]. However, it is possible to use hydrochloric acid hydrolysis as a way to get sound aqueous suspensions of CNFs.…”

“…The creation of nanocellulose fibres by mechanical treatment has been investigated in several academic works. The researchers, Lee et al, conducted a study to assess the appropriateness of non-woody fibres, namely paper mulberry bast fibre (PMBF) and cotton linter mixed pulp (CLMP), in the manufacturing process of nanocellulose [18]. Redlinger-Pohn and Lim conducted a study with the purpose of observing and quantifying events related to the flow of homogenization.…”

In recent times, there has been a discernible focus on the development of environmentally friendly and sustainable biomaterials obtained from renewable sources. Scientists are now investigating the prospective applications of nanocellulose, a biocompatible substance derived from natural cellulose. The aforementioned substance exhibits notable characteristics, such as a substantial surface area to volume ratio, with its compatibility with biological systems and capacity to undergo degradation. Nanocellulose has the capability to undergo transformation into nanofibers and nanocrystals, so enabling the generation of diverse structures, including elongated nanofibers, suspensions, and films. In the textile industry, there is a growing need to adopt sustainable techniques in order to address and minimize the negative environmental impacts. The current focus is on the advancement of environmentally sustainable alternatives in the realm of textile production, namely cellulose-based materials. These textiles are being created using processes that aim to minimize water pollution. In addition, recent advancements in dyeing methods have used nanocellulose to effectively reduce water consumption and eliminate the need for toxic materials. Nanocellulose nanocomposites, such as nanofibrillated celluloses (NFCs) and cellulose nanocrystals (CNCs), are increasingly used as fillers in textile nanocomposites to enhance their mechanical characteristics due to their cost-effectiveness and recyclability. The advancements achieved in the field of nanocellulose-based materials and technology exhibit considerable promise in the development of ecologically friendly solutions across several industries.

In this study, we conducted a fundamental investigation on the manufacturing of transparent films suitable for solar cell substrates using nanocellulose prepared from non-woody pulps. Cellulose nanocrystals (CNCs) were prepared using paper mulberry pulp, while quaternized cellulose nanofibers (Q-CNFs) and carboxymethylated cellulose nanofibers (CM-CNFs) were prepared using cotton lint mixed pulp (CLMP). The films were manufactured by adjusting the size of CNCs, zeta potential of CNFs, and CNC/CNF mixing ratio using a combined technique of vacuum-assisted and evaporation-induced selfassembly methods,depending on the type of nanocellulose. The thickness, transparency, and b* of the films were measured to determine the optimal manufacturing conditions. The films prepared with only the smallest CNC (Short-CNC) showed higher transparency than those prepared with a mixture of Short-CNC and the longest CNC (Long-CNC). The transparency of the films prepared with Short-CNC and Q-CNF decreased because of the flocs induced by the attractive interaction between them. Meanwhile, the films prepared with Short-CNC and CM-CNF showed high transparency because Short-CNC and CM-CNF comprised negative charges. The CNC/CM-CNF mixing ratio of 5:5 resulted in the highest transparency of the film. Therefore, highly transparent films suitable for solar cell substrates can be manufactured by combining CNCs and CM-CNFs.
