“…Those peaks correspond to

0, 110 and 020 lattice planes of the cellulose I crystalline form [ 20 , 21 ]. The locations of peaks were similar to those of plant celluloses [ 15 , 16 ] and BC [ 17 , 18 , 19 ]; however, their diffraction peaks were relatively less sharp. Therefore, the mechanical grinding process by using a ball mill might partially reduce the crystalline regions, leading to a higher proportion of the amorphous phase.…”

Natural Rubber Latex Foam Reinforced with Micro- and Nanofibrillated Cellulose via Dunlop Method

Natural rubber latex foam (NRLF) was reinforced with micro- and nanofibrillated cellulose at a loading content of 5–20 parts per hundred of rubber (phr) via the Dunlop process. Cellulose powder from eucalyptus pulp and bacterial cellulose (BC) was used as a microcellulose (MC) and nanocellulose (NC) reinforcing agent, respectively. NRLF, NRLF-MC, and NRLF-NC exhibited interconnected macroporous structures with a high porosity and a low-density. The composite foams contained pores with sizes in a range of 10–500 µm. As compared to MC, NC had a better dispersion inside the NRLF matrix and showed a higher adhesion to the NRLF matrix, resulting in a greater reinforcement. The most increased tensile strengths for MC and NC incorporated NRLF were found to be 0.43 MPa (1.4-fold increase) and 0.73 MPa (2.4-fold increase), respectively, by reinforcing NRLF with 5 phr MC and 15 phr NC, whereas the elongation at break was slightly reduced. Compression testing showed that the recovery percentage was improved to 34.9% (1.3-fold increase) by reinforcement with 15 phr NC, whereas no significant improvement in the recovery percentage was observed with MC. Both NRLF-MC and NRLF-NC presented hydrophobic surfaces and good thermal stability up to 300 °C. Due to their highly porous structure, after a prolong immersion in water, NRLF composites had high water uptake abilities. According to their properties, the composite foams could be further modified for use as green absorption or supporting materials.

“…Because the EPDM has much low crystallinity, it need to be reinforced through various methods, such as addition of fillers in engineering usage. such as carbon black [1][2][3][4][5][6][7][8][9][10][11], silica [12], fibers [13] and other filler particles. [14,15] Silica with the special structure, represents an important mineral material for common filler and engineering fillers, which can improve the mechanical properties of polymer matrix to reach excellent interaction between polymer and filler [16].…”

This paper studies how the addition of Carbon nanotubes (CNT) influencing the properties, especially the mechanical properties and colorimetry of ethylene propylene diene rubber (EPDM)/SiO2 composites. The results show that the increased content of CNT can turn EPDM/SiO2 composites from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/SiO2 composites would be acceptable when the CNT content is below 3%. When the CNTs content reaches 4%, the tensile strength of EPDM is the maximum.

Natural rubber latex foam (NRLF) filled with untreated and alkali/silane coupling agent‐treated jute fibers (JFs) were prepared using the Dunlop method. The JFs fillers were added at 0, 1, 3, and 5 phr. The density, crosslinking degree, and surface morphology of the untreated jute‐filled NRLF were studied, and the tensile and compression properties of the untreated and surface‐treated NRLF were compared. The results showed that the density, the modulus at 100% elongation (M100), and compression set of the untreated jute‐filled NRLF increased with increasing JFs filler content. The crosslinking degree, tensile strength, elongation at break, and recovery rate decreased with increasing JFs filler content. Regarding mechanical properties, the surface‐treated JFs‐filled NRLF exhibited higher tensile strength and M100 than the untreated group, indicating that alkali/silane coupling agent treatment enhanced the interaction between JFs and the matrix. However, the elongation at break was lower. As for the compression set and recovery rate, there was no significant difference between the two groups, indicating that alkali/silane coupling agent treatment had little effect on the compression set and recovery rate of JFs‐filled NRLF.
