“…The ester carbonyl groups observed at 1715 cm -1 and 1647 cm -1 are evidence of the reaction between OH groups (belonging to carboxylic groups of the collagen) and silanol groups on the surface of the silica particles [16]. This reaction is favored by the high electronegativity of oxygen and the lone pair of electrons of the carbonyl group and also by the acidic nature of SiOH groups.…”

“…Likewise, bands corresponding to Si-O-Si symmetric and asymmetric vibrations are located at 794 and 1080 cm -1 , respectively [15]. The signal at 948 cm -1 corresponds to the Si-OH group [16] while the wide one positioned in the range 3000 to 3750 cm -1 is attributed to the presence of hydroxyl groups [17]. Finally, peaks at 2929 and 2907 cm -1 are due to ethanol organic groups [18].…”

“…TEOS:H 2 O molar ratio, type of catalyst, etc.) employed for the synthesis of the nanohybrid solids; these SiO 2 cluster characteristics can induce a phase separation, thus influencing to a great deal the optical properties of the system [16]. Both the average SiO 2 particle size and the interfacial properties between collagen and silica matrix allow obtaining either transparent or opaque materials depending on the experimental conditions.…”

“…However, the stiffness and heat resistance properties of polymer matrix composites tend to be weakened if elastomers were the only additional components to the system. In contrast, nanoparticles, such as SiO 2 , Al 2 O 3 , mesoporous silica , etc. are able to drastically increase the stiffness and heat resistance.…”

MNSiO2/CN40/PF nanocomposites have been fabricated in this study. Nano‐SiO2 was initially surface‐modified with γ‐methacryloxypropyl trimethoxysilane (MPS). The resulting nano‐SiO2 was denoted as MNSiO2. Core‐shell composites, MNSiO2/CN40, was fabricated by a solution blending method, in which MNSiO2 served as the core and liquid acrylonitrile butadiene rubber (CN40) served as shell. Phenol formaldehyde resins (PF) were prepared by means of condensation polymerization method. MNSiO2/CN40/PF hybrid with a fixed weight ratio (2:98) of MNSiO2/CN40 composites to PF were prepared by a modified routine of preparation of pure PF. MNSiO2/CN40/PF nanocomposites were prepared by incorporating filler particles with MNSiO2/CN40/PF hybrid via melt blending, followed by compression molding method. The impact of MNSiO2 content on the properties of the MNSiO2/CN40/PF nanocomposites was systematically investigated by varying the weight ratio of MNSiO2 to CN40 in MNSiO2/CN40 core‐shell composites. The results revealed that MNSiO2/CN40 significantly enhanced the mechanical and frictional properties of the as‐prepared MNSiO2/CN40/PF nanocomposites. Compared to pure PF, the impact strength of MNSiO2/CN40/PF hybrid containing 1.0 wt% of MNSiO2 in MNSiO2/CN40 composites increased by 29.2%, and the initial storage modulus was enhanced dramatically. In addition, MNSiO2/CN40/PF hybrid demonstrated stable friction coefficient, while the wear mechanism of pure PF was adhesive and fatigue wear. The MNSiO2/CN40/PF nanocomposites exhibited a combination of adhesive, abrasive, and fatigue wear. POLYM. COMPOS., 40:179–186, 2019. © 2017 Society of Plastics Engineers

“…Phenol‐formaldehyde resin (PFR), known since 19th century, has been widely used as a common fire‐retardant and anti‐corrosive material . Recently, with the development of nanotechnology, PFR has attracted more attention due to its new great potential application in biological, environmental and energy field.…”

1D necklace‐like nanostructures have exhibited different potential applications due to their unique geometry and property. However, their macroscopic and controllable synthesis has been a challenge. Herein, a facile and scalable template‐directed hydrothermal process is reported to synthesize a series of necklace‐like phenol‐formaldehyde resin (PFR) wrapped nanocables. The 1D templates involved in the synthesis can be various, such as tellurium nanowires (TeNWs), silver nanowires, and carbon nanotubes. After removal of the TeNWs template, pure PFR necklace‐like nanofibers with different morphologies can be prepared. Owning to their multiscale roughness and formed 3D network structures, such necklace‐like PFR nanofibers can be further used as building blocks for constructing robust superhydrophobic coatings with excellent mechanical properties on various substrates.
