“…As shown in Figure 6A,B, in comparison with the spectra of the unmodified titanium dioxide, the absorption peaks at 928 and 1182 cm −1 appeared in the spectra of the amino‐modified titanium dioxide, corresponding to the Si‐O‐Ti and Si‐O‐Si stretching vibration absorption peaks, respectively 13,14 . The obvious characteristic peaks of amino‐modified titanium dioxide at 2887 and 2980 cm −1 were attributed to –CH 3 and –CH 2 stretching vibration absorption peaks, which suggested that the APS was successfully grafted onto the surface of the titanium dioxide 15 . Figure 6C shows absorption bands around 3340 cm −1 (N–H stretching) and 1530 cm −1 (N–H bending), which confirmed the formation of urethane linkage.…”

Polyurethane acrylate‐based titanium dioxide was used to prepare blue light‐curable inks as both a white pigment to replace the original white pigment and as an oligomer. The polyurethane acrylate‐based titanium dioxide was fabricated using a two‐step method. In the first step, the titanium dioxide was grafted with γ‐aminopropyltriethoxy silane, and the grafting process was studied. Second, amino‐modified titanium dioxide was used to prepare polyurethane acrylate‐based titanium dioxide, which was then used to configure the blue light‐curable polyurethane acrylate‐based titanium dioxide ink. Fourier Transform–infrared spectroscopy indicated that the amino‐modified titanium dioxide and polyurethane acrylate‐based titanium dioxide were prepared successfully. The content of the amino groups on the surface of the amino‐modified titanium dioxide could be effectively controlled by adjusting the pH value. Moreover, by increasing the content of the amino groups, the viscosity decreased and the photopolymerisation efficiency increased, which was attributed to the formation of branched structures and the promoting effect of the amino groups on the titanium dioxide. The inks with decreased viscosity and branched structures displayed excellent cross‐linking properties: viscoelastic transition was achieved within 10 seconds and the final moduli were in the range of 36‐55 kPa. The cross‐linking degree and rate were more than seven times those of unmodified ink. The ranges of elongation and stress were 95%‐165% and 1.9‐4.3 MPa, respectively, and the amino group content varied from 0% to 0.101%. In general, polyurethane acrylate‐based titanium dioxide was shown to be suitable for blue light‐curable ink.

“…In general, surface treatment or modification has been applied, particularly for the enhancement of the interfacial adhesion between components in composite systems. Among all the treatments, silane coupling agents impart the simplest way to introduce functional groups onto the surfaces of particles [45]. This treatment has been widely applied based on its simple process and no requirement for special equipment.…”

Natural cellulosic fibres, such as kenaf, can be used in polymeric composites in place of synthetic fibres. The rapid depletion of synthetic resources such as petroleum and growing awareness of global environmental problems associated with synthetic products contribute to the acceptance of natural fibres as reinforcing material in polymer composite structures. In Africa and Asia, kenaf is considered a major crop used for various cordage products such as rope, twine, and burlap and in construction, it is used for thermal insulation of walls, floors, and roofs and soundproofing solutions. In the furniture and automotive industry, it is used to manufacture medium-density fibreboard (MDF) and other composite materials for structural applications. Kenaf is primarily composed of cellulose (approximately 40 to 80%), which accounts for its superior mechanical performance. Kenaf fibres are chemically treated before mixing with the polymer matrix to improve their fibre interaction and composite performance. The alkaline treatment with sodium hydroxide (NaOH) solution is the most frequently used chemical treatment, followed by a silane treatment. Numerous chemical concentrations of NaOH and silane solutions are investigated and several combined treatments such as alkaline-silane. The present review discusses the effect of silane treatments on the surface of kenaf fibre on the fabrication of polymer composites and their mechanical properties.
