“…When DCP was heated, a large number of free radicals were released to initiate the interfacial grafting reaction of NaMAA between PP and EPDM due to its unsaturated carboxylic acid component. [ 41,45 ] At the same time, EPDM was cured by DCP. The complex free radical reactions among NaMAA, PP, and EPDM resulted in the good interface compatibility of the TPVs.…”

“…[ 35–39 ] The compatibilizer generated in situ exhibits better dispersion and smaller size, which can significantly affect the phase morphology of TPVs and the size of the rubber domains. [ 40–42 ] Mani et al [ 43 ] prepared an in situ formed grafted copolymer, which reduced the diameter of the polydimethylsiloxane from 16.5 to 0.6 μm. In most cases, the addition of a compatibilizer may improve both tensile strength and elongation at break of TPVs and decrease the diameter of rubber particles.…”

Increasing the interfacial adhesion with compatibilizer has been proved to be an effective method to enhance the mechanical properties of composites. In this paper, sodium methacrylate (NaMAA) was introduced to enhance the interfacial adhesion between polypropylene (PP) and ethylene propylene diene monomer (EPDM) via the peroxide‐induced dynamic vulcanization. NaMAA‐induced compatibilization enhanced the phase interface efficaciously and reduced the diameter of EPDM particles from ~8 to ~4 μm. Silica (SiO2) was used in the matrix to improve the mechanical properties of the thermoplastic vulcanizates (TPVs). It was found that SiO2 had little influence on the compatibility between EPDM and PP; however, it improved the tensile strength and stiffness of the TPVs without a severe reduction in the elasticity. The interfacial compatibility of modified EPDM/PP TPVs was verified by Fourier transform infrared, rubber process analyzer, and scanning electron microscope. With 3 wt% of NaMAA and 12 wt% of SiO2, the tensile strength improved from 8.5 to 12.7 MPa and the elongation at break was ranged from 320% to 410%.

“…Meanwhile, the thermoplastics explored include polypropylene (PP), high-density polyethylene, polyamide (PA), and polyurethane. 12 − 25 EPDM/PP TPVs 4 , 26 are currently the first commercial TPV products, mainly because the good compatibility between EPDM and PP results in finely dispersed rubber particles without any compatibilizer.…”

Presenting a combination of sustainability and environmental friendliness, a new class of green and non-petroleum-based thermoplastic vulcanizates (TPVs) was successfully developed from silica-filled silicone rubber (FSR) and poly(butylene succinate) (PBS) via dynamic vulcanization. The phase morphology, interfacial compatibilization, and microstructural properties of FSR/PBS TPVs were investigated. Notably, a large number of FSR microparticles were observed and were dispersed in the continuous PBS phase, indicating complete phase inversion during the dynamic vulcanization. The fine phase morphology of FSR/PBS TPVs was achieved by a fine phase morphology of the SR/PBS premix, the good interfacial compatibility between the PBS phase and the cross-linked FSR phase, and complete phase inversion. The as-prepared TPVs possessed high tensile strength, good elastic behavior, easy processability, and reprocessability. These novel non-petroleum-based TPVs have potential applications in packagings, biomedical devices, and three-dimensional (3D) printing materials.

Commercial rubber is hardly considered as raw materials to manufacture multifunctional shape‐memory polymers (SMPs) because it is difficult to either tune its glass transition temperature or introduce crystalline domains. Here, we report the manufacture of luminescent SMP composites based on commercial carboxylated nitrile rubber and rare earth organic complex (REOC) with Sm3+ ions. The dispersion of REOC and the properties of the composites were investigated in detail. The increase in the REOC loading did not deteriorate the tensile strength and elongation at break of the composites, when the stresses at low strains were highly improved. The strong filler‐chain interaction increased the glass transition temperature of the rubber composites. Besides, luminescent functions were introduced into such rubber composites, while luminescent intensities and lifetime can also be affected by REOC loadings. Finally, the prepared rubber composites presented a light‐induced shape‐memory effect under the irradiation of near‐infrared light due to the photothermal effect of the REOC.
