Purpose This paper aims to investigate the crucial roles of textured surfaces on oil-impregnated polytetrafluoroethylene (PTFE) created by a facile tattoo strategy in improving tribological properties. Design/methodology/approach Pored PTFE (PPTFE) was prepared mixing powder and citric acid experienced cold-press sintering molding process. Subsequently, were obtained with using strategy. Surface-textured PPTFE thus impregnated polyethylene glycol 200, yielding pore-connected PPTFE. Findings...
Dually crosslinked graphene oxide reinforced alginate/polyvinyl alcohol (PVA) double network (DN) hydrogels were prepared via a facile freeze/thaw method followed by soaking in Ca2+ solution. The morphology and structure of the systematically examined Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA). effects pH, dosage hydrogel, adsorption time, temperature on adsorptive property DN towards methylene...
Purpose This paper aims to regulate the oil retention rate and tribological properties of pored polytetrafluoroethylene (PPTFE) using polyvinyl alcohol (PVA)-based gel. Design/methodology/approach PPTFE was first prepared by citric acid (CA) as an efficient pore-making agent. Subsequently, PVA chitosan solution introduced into pores experienced a freezing-thawing process, forming PVA-based gels inside pores. Then, PPTFE/PVA composite impregnated with polyethylene glycol 200 (PEG200),...
Abstract The chemical inertness of the basalt felt (BF) results in a weak interface bonding between BF and polymer matrix, which hinders further application reinforced composites. In this study, nickel‐based metal–organic framework (Ni‐MOF) sheets were decorated on surface by facile one‐step hydrothermal method to improve interfacial epoxy resin (EP) matrix embed solid paraffin. mechanical tribological properties EP composites with evaluated. shear strength (IFSS) was measured single‐fiber...
Ru nanoparticles doped and supported by Mo oxide (Ru/Mo NPs) were synthesized via an in situ co-precipitation strategy for hydrogen production hydrolysis of ammonia borane (AB). The optimized Ru0.9Mo0.1 catalyst composition exhibited a total turnover frequency (TOF) value 514.8 molH2 (molRu0.9Mo0.1)−1 min−1 at room temperature. Systematic characterization the catalysts unveiled dual role regulating structure catalytic performance NPs. This work provides new approach design Ru-based...
Abstract Epoxy composites with simultaneously enhanced tribological and mechanical properties filled basalt belt/reduced graphene oxide/paraffin wax (EP/BF/RGO/PW) have been successfully prepared. Experimental results indicated that the property of was reinforced by belt, greatly improved reduced at same time. Thanks to synergy PW RGO sheets, optimized coefficient friction wear rate composite declined 77.5% 14.4% than pure EP under dry conditions 60 N 0.42 m s −1 . In comparison EP, tensile...
A transition‐metal‐free procedure for synthesizing tri‐aryl substituted α‐pyrones has been developed. It involves conjugate addition, C‒O bond formation and cleavage. This provides an efficient protocol the synthesis of multi from readily available starting materials. Notable features this program are high atom economy transition‐metal‐free.
Polyamide 11/graphene coatings were prepared through a spraying method with as-prepared organophilic graphene. The tribological results showed that the wear life of composite was obviously higher than neat 11 coating; however, values friction coefficients had hardly changed. optimal content graphene in range our experiments 0.4 wt%, and coating increased by 460%–880% compared pristine coating. morphology worn surface for both composites studied, mechanisms discussed.
Polyphenylene sulfide (PPS) composite coatings reinforced by graphene were prepared through a spraying method. Wear performance of the evaluated using block-on-ring test rig, and results showed that wear life over seven times higher than pure PPS coating. mechanisms are discussed. It was concluded adhesive major mechanism coating but form dominated abrasive due to filler has high mechanical strength. In addition, fatigue appeared for with content graphene. The formation uniform thin transfer...
