Since CNFs are one of the new materials that can fulfill the goals of the Sustainable Development Goals (hereafter abbreviated as SDGs), many researchers have been studying the nano-fibrillation of wood fibers. From the viewpoint of SDGs, it is necessary to avoid using a large amount of chemical agents and consuming a large amount of energy for the production of CNFs. To realize these requirements, it is important to find a way to industrially utilize CNFs containing insufficiently nanosized fibers, and for these purposes, it is essential to evaluate the physical properties of these CNFs from multiple perspectives. Cellulose fibers are intrinsically insulating materials, but how their electrochemical properties are changed by nano-fibrillization has been little studied. Therefore, we decided to clarify the relationship between the size of CNFs and the electrochemical impedance properties of the CNF suspensions containing un-fibrillated fibers, which were prepared by a wet refinement system. The fiber diameter remained constant as the number of mechanical treatments (hereafter referred to as the “number of collisions”) increased. On the other hand, the cumulative medium volume diameter, D₅₀, defined as the apparent fiber length (hereafter referred to as the “fiber length”, in microns), significantly decreases with the increasing number of collisions. The rheo-impedance |Z| of the CNF suspension remained nearly constant in the intermediate frequency range of 10³–10⁶ Hz, even if the internal structure of the system was deformed by the increasing shear rate. This means that the electrochemical properties of the CNFs are independent of the changes in the macroscopic aggregation structure. Furthermore, the internal resistance <i>R</i>₁ calculated from the impedance |Z| characteristics (Nyquist plot) became decreased with the increasing number of collisions, indicating a proportional relationship between the resistance <i>R</i>₁ and the CNF fiber length, D₅₀. This suggests that <i>R</i>₁ related to the resistance caused by the electrolyte in the suspensions or the protons dissociated by the hydration of the hydroxyl groups of the cellulose molecule as they move across the gaps between the microfibrils. Based on these results, it appears that the electrochemical properties of the CNF suspensions are independent of the changes in the macroscopic aggregation structure and simply depend on the fiber length, in other words, the electrochemical properties are a useful method for indirectly evaluating the fiber length of the CNFs.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 18","pages":"10771 - 10784"},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-024-06242-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142754231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphological analysis was performed using atomic force microscopy (AFM): purified CNCs had an average length of 183.1 ± 73.9 nm, unpurified CNCs had an average length of 202.0 ± 79.2, and both samples had an average diameter of 4 ± 2 nm. Mechanical analysis of individual CNCs using force-distance spectroscopy (FDS) suggested both samples had little differences with average values of Young’s modulus 2.19 ± 0.15 GPa, maximum loading force of 6.29 ± 0.09 nN, and adhesion energy of 1.57 ± 1.12e-16 J. No statistical differences between purified and unpurified CNCs were found in Young’s modulus and maximum loading forces measurements, suggesting the impurities had minimum impact on mechanical strength.

One limitation of dense CNM films is their lack of durability due to their brittle nature. The durability of cellulose nanofibril (CNF) films was examined through the lens of understanding the residual stress that formed within the films during drying. A beam bending method consisting of drying CNF films on top of a flexible substrate was used to quantify residual stress. It was determined that for two common variations of CNFs (TEMPO-oxidized vs mechanically refined), the residual drying stress was on the order of 50% of the yield strength of the material at a given humidity. Larger residual stress formed within the TEMPO-oxidized CNFs as compared to the mechanically refined CNFs due to the smaller fibril diameters resultant of the TEMPO oxidation production process. The residual stress in the TEMPO-oxidized material was also more sensitive to moisture (humidity) than the mechanically refined material. Various plasticizers were examined for their efficacy in reducing residual drying stress. Triethyl citrate appears more effective in reducing residual stress than common polyols (glycerol/sorbitol), especially when subjecting the films to low humidity. Triethyl citrate in combination with a small amount of polyvinyl alcohol at a total plasticizer content of 30% of the mass of the CNFs resulted in a 75% reduction in the residual stress from the unplasticized state. In this low-stress state, standalone films (10–15 µm) can withstand creasing operations that compromise unmodified (high residual stress) films in terms of their ability to prevent oxygen transmission. Additionally, the low-stress formulation was coated onto a paper substrate resulting in enhanced durability during creasing operations prior to oxygen barrier testing.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"31 18","pages":"10845 - 10859"},"PeriodicalIF":4.9,"publicationDate":"2024-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This material was achieved through an electrically charge-controlled layer-by-layer self-assembly of chitosan and titanium dioxide nanoparticles (TiO₂ NPs), followed by functionalization with carnauba wax (CW).
