“…The contact angle test was applied to characterize the polarity of samples, which could reflect its wettability and display a substantial correlation with the adhesion property in some bonding systems. [29][30][31] The surface energy of the PPS surface was calculated using Neumann equation 32 : In Neumann's approach, g LV is the surface tension of the liquid in equilibrium with its own vapor, represents the contact angle, g s is the surface tension of the solid in equilibrium with the saturated liquid vapor, which can be regarded as the surface energy, and is an empirical constant that depends on the system under investigation but is typically set to be equal to 0.0001247 (mJ m À2 ) À2 . 32 Figures 6 and 7 demonstrate the contact angle and surface energy of PPS surface after air DBD plasma treatments with different parameters.…”

Air dielectric barrier discharge (DBD) plasma was employed to treat the sanded polyphenylene sulfide (PPS) surface. The plasma-treated PPS samples were bonded with epoxy adhesive, and the adhesion strength was measured by the single lap-joint specimen test. Scanning electron microscopy (SEM), water contact angle analysis, and X-ray photoelectron spectroscopy (XPS) were applied to investigate the effect of the plasma treatment on the PPS surface property. A slight etching trace was detected after the plasma treatment according to the SEM images. XPS and water contact angle analysis indicated that the plasma treatment introduced sulfide oxides (S¼O and O¼S¼O) onto the PPS surface leading to a higher surface energy. A steady improvement of bonding shear strength was achieved with the increase of plasma treatment time or discharge power density, which was consistent with the failure mode study. According to the above analysis, the air DBD plasma treatment could effectively improve the adhesion property of PPS.

“…Accordingly, some attempts have been made to prepare FKM/SR blends, combining the excellent oil resistances properties of FKM and low temperature resistances of SR. By mechanical blending, the FKM/SR blends are expected to partially substitute expensive fluorosilicone rubber to some extent [15][16][17] . However, after vulcanization, the cured FKM/SR blends are thermosetting material.…”

Thermoplastic vulcanizates (TPVs) based on poly (vinylidene fluoride) (PVDF), silicone rubber (SR) and fluororubber (FKM) were prepared via dynamic vulcanization. Morphology characterization showed that spherical rubber particles were dispersed separately and "connected" by "bridge" in the TPV with 10 wt.% FKM, but agglomerated together with higher FKM content. The mechanical properties of TPVs were improved, especially tear strength and elongation increased from 24 kN.m À1 and 23% to 103 kN.m À1 and 306%, respectively, with FKM increased from 10 wt.% to 50 wt.%. Rheology studies and dynamic mechanical properties results showed that the compatibility between PVDF and rubber phase was improved by FKM.

“…They proposed that 75 wt% of FKM and 25 wt% of MVQ combines superior compatibility. [ 26 ] The effect of FKM‐g‐vinyltriethoxysilane in the FKM/MVQ rubber blend as an effective compatibilizer has also been studied and the results showed that 9 phr loading of the compatibilizer enhances the mechanical, thermal properties and improves filler to rubber interactions. [ 27 ] Wang et al have studied the dynamically cured polyvinylidene fluoride (PVDF)/MVQ/FKM blend system with the partial replacement of MVQ with FKM.…”

The study presents the preparation of acrylamide grafted fluoroelastomer (FKM‐g‐acrylamide) by melt mixing process and its evaluation as a reactive compatibilizer for fluoroelastomer (FKM) and methyl vinyl silicone rubber (MVQ) blend system (at different compositions) in terms of mechanical properties, thermal stability, aging behavior, and morphological aspects. Mechanical properties investigation discloses almost 20% increment in tensile strength after the incorporation of 3 parts per hundred rubber of FKM‐g‐acrylamide into the FKM/MVQ blend. The shifting of the Tgs of both the rubber phases toward each other along with the decrease of the heat capacity value (Cp) attest the effective compatibilization role of the compatibilizer. However, no significant changes in the thermal stability of the blends are observed after incorporation of the prepared compatibilizer. The heat and oil aging behavior shows remarkable percentage retention of the mechanical properties for the compatibilized blend system compared to the uncompatibilized one. The morphological study indicates the abrupt reduction of the FKM domain size (2000–180 nm) in the MVQ matrix for the compatibilized blend.
