“…5. Comparing with DCPDCE, the maximum curing temperature of POSS-SiO 2 /DCPDCE shifts to lower temperature with a gap of about 10 C, demonstrating that the curing process of DCPDCE can be accelerated by a small amount of POSS-SiO 2 loading. The decreased curing and postcuring temperature is beneficial to manufacture cyanate ester-based composites for industrial application.…”

In this article, a hybrid filler based on polyhedral oligomeric silsesquioxane and silica, coded as POSS-SiO 2 , has been successfully synthesized. The structure of POSS-SiO 2 was studied by Fourier-transform infrared spectra, X-ray diffraction, and scanning electron microscopy. Then the POSS-SiO 2 was compounded with dicyclopentadiene bisphenol dicyanate ester (DCPDCE) resin to prepare composites. The effects of POSS-SiO 2 on the curing reaction, mechanical, thermal, dielectric and tribological properties of DCPDCE resin were investigated systematically. Results of differential scanning calorimetry show that the addition of POSS-SiO 2 can facilitate the curing reaction of DCPDCE and decrease the curing temperature of DCPDCE. Compared with pure DCPDCE resin, the impact and flexural strengths of the composites materials are improved markedly with up to 72 and 52% increasing magnitude, respectively. Meanwhile, the POSS-SiO 2 /DCPDCE systems exhibit lower dielectric constant and loss than pure DCPDCE resin over the testing frequency

“…Therefore, their toughening has been an important topic for both scientists and engineers. Several techniques have been developed to improve the toughness of thermosetting resins; these include (1) using inorganic nanoparticle modifiers for the stress‐concentration region, (2) using reactive and nonreactive rubber modifiers designed for phase separation upon curing, and (3) using nanostructured thermoplastic fiber mats for interlaminar toughening . However, these techniques still have some limitations.…”

A thermotropic acetylene-terminated liquid-crystal monomer, 2-methyl-1,4-phenylene bis(4-ethynylbenzoate) (MPBE), was prepared and used as a modification composition to react and cocure with a silicon-containing arylacetylene (PSA) oligomer for improving PSA resin. The curing behavior of the PSA-MPBE resins were characterized by differential scanning calorimetry and Fourier transform infrared spectroscopy. The microstructure and morphology of the PSA-MPBE resins were investigated by scanning electron microscopy (SEM) and transmission electron microscopy. Their dynamic mechanical properties and thermostability were measured by dynamic mechanical analysis (DMA) and thermogravimetric analysis. The results indicate that the thermotropic acetylene-terminated liquid-crystal monomer melted into a schlieren texture. MPBE and PSA could copolymerize to fix the mesogenic domain in the crosslinked network and form a homogeneous-phase sea-island structure, which improved the rigidity and toughness of the materials. DMA showed that the storage modulus of the PSA-MPBE resins increased by about 400 MPa compared to the those of the pure components. The SEM experiments showed a noticeable change in the morphology, from a typical brittle fracture for the pure PSA to microplastic deformation behavior for the PSA-MPBE resins.

“…Therefore, it has been a hot topic during the last decade to modify and toughen cyanate ester resins. In recent years, adding reinforcing nanofillers, such as surface‐treated silica , carbon fibers , CNTs , bentonite clay , and GNSs to the thermosetting polymer matrix is an effective way to enhance toughness performance which can meet the application requirements.…”

Effects of surfactant treatment on mechanical and microwave absorbing properties of graphene nanosheets/multiwalled carbon nanotubes/cyanate ester composites

Graphene nanosheets (GNSs) and multiwalled carbon nanotubes (MWCNTs) were treated with a nonionic surfactant polyvinylpyrrolidone (PVP), and its effects on dispersion state, surface chemistry, structure, and morphology of MWCNTs and GNSs, as well as on the microwave absorbing properties, mechanical properties of GNSs/MWCNTs/cyanate ester nanocomposites were analyzed respectively. Results show that surfactant plays an important role in dispersing the GNSs and MWCNTs in a solvent and polymer. The mechanical properties, such as impact fracture toughness and flexural strength all showed significant improvements after the treatment. The above observations are attributed to the unique amphiphile structures of PVP, which improved the interface characteristic between matrix and the fillers. Besides, PVP can effectively enhance interfacial interactions which gave rise to improved dispersion and wetting of GNSs and MWCNTs in polymer matrix. Unlike chemical functionalization techniques, however, the surfactant treatment exhibited little adverse effect on microwave absorption properties of the nanocomposite. POLYM. COMPOS.,
