“…Table 2 summarizes the DB and ANB values of HPSis. It can be seen that HPSis have approximate DB and ANB values with those derived from single MPS [40], suggesting that the rate of co-hydrolysis and polymerization of two silanes is approximate to that of single silane. In addition, as the molar ratio of silanes to H 2 O decreases, the resultant HPSi has higher DB and ANB values, reflecting that more methoxy groups have been transformed into siloxane groups, providing more ability to take part in the polymerization, so the resultant HPSi has larger weight-average molecular weight (M w ).…”

“…1 shows the FTIR spectra of four HPSis and the GPTMS/MPS blend. Each spectrum exhibits the characteristic absorptions of epoxy groups (907 cm −1 ) and C=C bonds (1455 cm −1 ), but there are two additional peaks assigned to the bending vibration peak of -Si-OH (3450 cm −1 ) and -Si-O-Si-(1000-1200 cm −1 ), meaning the occurrence of the hydrolysis and polymerization [40,41].

“…[14][15][16] However, the structure and properties of the interphase can directly a®ect the performance of composite materials 17 ; thus, the e®ective interphase is important for further improving the interfacial adhesion between MWCNTs, the resin and the nano¯llers. Hyperbranched polymer is a new type of polymer that has a highly branched, nonentangled architecture and active terminal groups, 18,19 leading to low viscosity and lower viscosity. [20][21][22] Hyperbranched polysiloxane (HPBSi) not only has the advantages mentioned above but also exhibits the advantages of polysiloxane, such as good thermal and moisture resistance.…”

To reveal the wear mechanism of hyperbranched polysilane (HBPSi) grafted multi-walled carbon nanotubes (HBPSi-MWCNTs) modi¯ed benzoxazine-bismaleimide (BOZ-BMI) resin (HBPSiMWCNTs/BOZ-BMI), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) were employed. The results indicated that the suitable addition of HBPSi-MWCNTs could largely enhance the tribological properties of BOZ-BMI composites. The worn surface of the composites showed that the severe wear of the BOZ-BMI resin was converted from adhesive wear to abrasive wear with the addition of HBPSiMWCNTs. The excellent tribological properties can be attributed to the improved interfacial adhesion between HBPSi-MWCNTs and the BOZ-BMI resin matrix. The TGA demonstrated that the composite with 0.8 wt.% HBPSi-MWCNTs exhibits better thermal resistance; thus, it can inhibit adhesive wear during the friction process. The XPS spectra and the surface energy showed that the HBPSi-MWCNTs could be exposed on the worn surface of the composite to improve the anti-wear capacity of the composites further.

“…Many methods have been developed to overcome this deficiency. For instance, developing alternative monomers with lower viscosity by elimination of hydrogen bond donor groups has been adopted by several researchers . Applying multifunctional acrylate monomers as reactive diluents has also been proved to be an effective way, but often at the expense of film properties as it can cause brittleness and shrinkage problems .…”

The dimethacrylate reactive diluent (HEMA‐DDSA), a long‐side‐chain‐containing reactive diluent, was prepared by reacting 2‐dodecen‐1‐ylsuccinic anhydride with two equivalents of hydroxyethyl methacrylate. Its structure was characterized by IR and 1H NMR spectroscopy. This new diluent was added into the formulation of UV‐curable epoxy acrylate networks. Results show that the formulation with the addition of HEMA‐DDSA has massively reduced viscosity and shows several attractive properties of epoxy acrylate oligomers. The mechanical resistance of the films is dramatically enhanced with the incorporation of long alkyl groups derived from HEMA‐DDSA, the plastic deformation zone expands, thus decreasing the inner stress of the polymer structure. Moreover, the cured coatings have a higher glass transition temperature as the percentage of HEMA‐DDSA is increased up to 5 wt%. Due to the excellent integrated performance of the polymeric films, HEMA‐DDSA proved to be an effective reactive diluent, which is of potential interest for applications in high performance materials. © 2016 Society of Chemical Industry
