“…From the previous results, it was obvious that the modified nRHP–EPDM nanocomposites exhibited higher strength, hardness, and lower elongation at break values than those of unmodified nRHP–EPDM nanocomposites which was referred to the presence of MA‐g‐EPDM copolymer segments on the surface of the modified nRHP nanocomposites, which enhanced the dispersion of nRHP in EPDM matrix and increased the interaction between nRHP and EPDM matrix. Similar observations were previously reported by many researchers .…”

“…From the previous results, it was obvious that the modified nRHP-EPDM nanocomposites exhibited higher strength, hardness, and lower elongation at break values than those of unmodified nRHP-EPDM nanocomposites which was referred to the presence of MA-g-EPDM copolymer segments on the surface of the modified nRHP nanocomposites, which enhanced the dispersion of nRHP in EPDM matrix and increased the interaction between nRHP and EPDM matrix. Similar observations were previously reported by many researchers [7,15]. Figure 5 shows the swelling percentage of unmodified and modified nRHP-EPDM nanocomposites for 24 h. It was found that swelling percentage decreased by increasing the filler loading, which indicated that higher amount of nRHP restricted the penetration of toluene in the nanocomposites.…”

Assessment of modified rice husk powder/ethylene propylene diene monomer (EPDM) nanocomposites for biomedical applications

The nanocomposite of nano rice husk powder (nRHP)–ethylene propylene diene monomer (EPDM) was prepared from modified nRHP and EPDM with different formulations containing 0–100 parts of modified nRHP per 100 parts of EPDM using curing process and laboratory size two roll mill. The surface of nRHP was modified by grafting MA‐g‐EPDM copolymer on its surface to enhance the compatibility between nRHP and EPDM. MA‐g‐EPDM copolymer was successfully prepared by melt method. The effect of filler (nRHP) loading on the mechanical and morphological properties of the modified nRHP–EPDM nanocomposites was investigated compared to the unmodified nRHP–EPDM nanocomposites (blank). Successive study was carried out on the nRHP–EPDM nanocomposites by means of human gingival fibroblast (HGF) as a fine source of human cell lines to test the cytotoxicity of the prepared nanocomposites by using 3‐(4,5‐dimethylthiazol‐2‐yl)‐2, 5‐diphenyltetrazolium bromide (MTT). The in vitro study indicated that the prepared nanocomposites were non‐toxic for HGF and could be developed for future medical uses. POLYM.

“…The significant differences in the value shows that the lower percentage of rice husk will decrease the hardness of the material as the bonding between the molecules become irregular. [18] also indicated that, the rice husk fibers increase the value of hardness composites. Increasing rice husk ash loading in natural rubber/linear low density polyethylene increased hardness [17].…”

Abstract-This paper presents the development of hybrid composites mechanical properties. In the experiments carried out, Polypropylene (PP), Rice Husk (RH) and short E-Glass (EG) fibers are prepared through the process of melt-mixing technique at 175 0 C for 8 minutes and 50rpm rotor speed using an internal mixer (Haake Rheomixer Machine). The hybrid composites made are prepared in various ratios of fiber weight fractions varying up to 60% where the treatment of rice husk using 2% concentration of Sodium Hydroxide (NaOH) to improve the interaction and adhesion between the nonpolar matrix and the polar lignocellulosic fibers. The specimens are analyzed by different techniques, such as tensile test, impact test, hardness test and Scanning Electron Microscopy (SEM). The presence of NaOH in rice husk for 15% indicates higher tensile strength and impact strength, while the tensile modulus and hardness strength is, however, reduced. The morphology results support the tensile properties which indicated the interaction between the PP and fibers with addition of NaOH. These results recommend that rice husk and EGlass fibers are a viable alternative to hybrid-based reinforcing fibers as long as the right processing conditions are applied and they are used in the applications.

“…The compounds with 25 phr of TMF showed increased tenacity in the range [4][5][6][7][8] An interesting endpoint emerges at the 10 phr level of MAPE where the tenacity values were similar for 25 and 40 phr of TMF.…”

The effect of the addition of maleated polyethylene (MAPE) to compounds of natural rubber (NR) and Telinne monspessulana flour (TMF) previously mercerized was investigated. Two factors were analyzed: A. concentration of MAPE with five levels 2; 4; 6; 8; 10 phr (parts per hundred rubber), B. concentration of TMF with two levels 25 and 40 phr. The effect of MAPE on compatibility between NR and HTM was evaluated by tensile testing the compounds. The mixing was performed in a laboratory scale mill. The test tubes were obtained by cutting or die-cutting crosslinked peroxide sheets, these were obtained during the compression molding process. Analysis indicate that the MAPE coupling agent improved the compatibility between HTM and NR, this effect was evidenced by the values of tensile strength and elongation at break. However, the gel content determination indicates that the addition of 10 phr of MAPE crosslinking decreases due to competition with coupling reaction MAPE -HTM.
