“… 130 The use of NCC with zinc oxide as fillers formed Zn–cellulose through the formation of ionic bonds, improving the dispersion of both fillers in the NBR matrix and resulting in a composite with superior mechanical properties than both singly filled-NBR. 131 Other recent works involving modification of NCC filler for synthetic rubber is summarized in Table 2 .…”

“…At 2895 cm À1 , the band corresponds to the stretching of the CH group; in 1035 cm À1 to the CO stretch, due to the presence of pyranose and a band in 897 cm À1 of the β-glycosidic bond between glucose, to form cellulose. 17 Aromatic oil, a mineral oil formed by hydrocarbons, has characteristic bands shown in Figure 2(b). The bands at 2921 cm À1 and 2860 cm À1 represent the stretching of the CH 2 group.…”

Silica and carbon black (CB) are the most used reinforcement fillers in elastomeric compositions; however, their obtention and usage might result in environmental and human health damages. The same happens to the plasticizers used in elastomeric compounds, which contain a high content of polycyclic aromatics. To use reinforcement and plasticizer loads from natural sources, the performance of an elastomeric compound by partially replacing CB with nanofibrillated cellulose (CEL) provided with Eucalyptus spp. shavings was evaluated in this work, as well as, the use of palm oil to replace aromatic oils. Nanofibrilated cellulose was obtained by grinding in a micronizing mill. As a characterization of the raw material, the thermal, chemical and morphological properties, as well as particle size analysis of the cellulose suspension were evaluated by the particle size analyzer. From the vulcanized material, the physical, mechanical, dynamic-mechanical properties, cross-link density, and swelling index in solvents were evaluated. As the main results obtained, the presence of CEL clusters seen by scanning electron microscopy with nanofibers with diameters of 100–85 nm was observed. The dynamic light scattering particle size analyzers (DLS) showed nanoparticles from 1 to 100 nm. The rheometric properties showed lower values for the parameters of safety time, optimal vulcanization time, and maximum and minimum torques when compared to samples with CEL as CB. For tear resistance properties, samples with the presence of nanofibrilated cellulose showed 48% more resistance than samples with CB, in the modulus of elasticity, cross-link density, and swelling index, a better performance was also achieved for the samples with CEL, along with presenting a similar behavior in the hardness property between samples with the presence of nanofibrillates and those with CB. Palm oil, a substitute for aromatic oil, was found to be similar in the evaluated properties results, with interaction with CEL, by chemical affinity, which can replace aromatic oil.

“…240 The percolation network can be formed at lower concentrations with good dispersibility of the CNC. 241 Some studies judged the dispersibility of the CNC from the fit of the mechanical model. The Cox-Krenchel model was in good agreement with the actual modulus under the assumption of a perfect elastic bond between the model filler and the matrix.…”

Cellulose nanocrystals (CNCs) are hydrophilic nanoparticles extracted from biomass with properties and functions different from cellulose and are being developed for property-oriented applications such as high stiffness, abundant active groups, and biocompatibility. It has broad application prospects in the field of composite materials, while the dispersibility of the CNC in polymers is the key to its application performance. Many reviews have discussed in-depth the modification strategies to improve the dispersibility of the CNC and summarized all characterization for the CNC, but there are no reviews on the in-depth exploration of dispersion characterization. This review is a comprehensive summary of the characterization of CNC dispersion in the matrix in terms of direct observation, indirect evaluation, and quantified evaluation, summarizing how and why different characterization tools reveal dispersibility. In addition, "decision tree" flowcharts are presented to provide the reader with a reference for selecting the appropriate characterization method for a specific composite.
