Preparation of an aminographene–aliphatic hydroxyl-terminated polysiloxane hybrid for synergistic enhancement of the mechanical and tribological performance of monomer casting nylon 6

Abstract

UFG-AHPDMS hybrid with covalent linkages was prepared by chemical grafting and reduction reaction of GO and urea, and then through reaction with AHPDMS using TDI as a bridge in CL...

Improve the thermal properties of oil‐loaded polysulfone microcapsules by optimizing copper layer for self‐lubricating polyamide

“…When the microcapsule content was 20 wt.%, the tensile strength of PA6 composites reduced from 70.2 MPa of pure PA6 to 35.4 MPa, and the elongation at break was reduced from 27.5% to 5.6%. The significant reduction in tensile properties could be attributed to the large diameter of the microcapsules on the one hand, and the fact that the microcapsules contained liquid lubricating oil on the other hand, so the microcapsules acted as a soft material in the polymer matrix 47 …”

“…The significant reduction in tensile properties could be attributed to the large diameter of the microcapsules on the one hand, and the fact that the microcapsules contained liquid lubricating oil on the other hand, so the microcapsules acted as a soft material in the polymer matrix. 47 COF and wear rate were tested to evaluate the tribological properties of self-lubricating PA6 composites. The COF curve of PA6 had great fluctuation, and the average COF was 0.22.…”

Design and synthesis of ammonia-modified reduced graphene oxide possessing more amino groups for methylene blue adsorption

“…1 These materials can be used as adsorbents. 2–4 Organic small molecules, polymers, or inorganic compounds have been used to functionalize GO or RGO, and the products are adsorbents with high capacity. 5–9 The adsorption capacity would be enhanced when functional groups were attached to graphene sheets.…”

Study on Reinforcing and Toughening Modification of MC Nylon

“…Currently, PTW has been proved to be a favorable reinforcement to modify MC nylon, having the merits of a large aspect ratio, high strength, and good rigidity. The introduction of PTW as a reinforcement of MC nylon can improve the strength, modulus, wear resistance and dimensional stability of nylon [11][12][13]. In addition to the advantages unique to nanomaterials such as surface effect and small-size effect, AlNPs have the characteristics of high hardness, high-temperature resistance, and wear resistance, allowing them to be widely used in various plastics, rubber, ceramics, and more for reinforcement and toughness improvement [14,15].…”
