“…However, when further increasing the dosage of TiO 2 -KH550, the TS decreased. At a high dosage, nanoparticles tended to aggregate to reduce the surface free energy, which led to a decrease in the hydrogen bonding between TiO 2 -KH550 and the polymers [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. It should be noted that a strong interaction between TiO 2 -KH550 and PVA/xylan matrix affected the mobility of PVA and xylan molecules and decreased the EAB value of the composite film.…”

“…Therefore, dispersants have to be added to improve the dispersion of nanoparticles in the medium. Inorganic phosphates can reduce the particle aggregation by changing the surface charge distribution like anticoagulants [ 25 , 26 ]. For instance, sodium hexametaphosphate (SHMP), an inorganic anionic surfactant, has been used for nanoparticle dispersion.…”

In order to improve the strength of polyvinyl alcohol (PVA)/xylan composite films and endow them with ultraviolet (UV) shielding ability, TiO2-KH550 nanoparticles was synthesized and added into the PVA/xylan matrix. The TiO2-KH550 nanoparticle dispersed well in the 0.04% sodium hexametaphosphate (SHMP) solution under ultrasonic and stirring treatments. Investigations on the properties of the films showed that TiO2-KH550 had the positive impact on improving the strength, moisture, and oxygen barrier properties of the composite films. The maximum tensile strength (27.3 MPa), the minimum water vapor permeability (2.75 × 10−11 g·m−1·s−1·Pa−1), and oxygen permeability (4.013 cm3·m−2·24 h−1·0.1MPa−1) were obtained under the addition of 1.5% TiO2-KH550. The tensile strength of TiO2-KH550 reinforced composite film was increased by 70% than that of the pure PVA/xylan composite film, and the water vapor and oxygen permeability were decreased by 31% and 41%, respectively. Moreover, the UV transmittance of the film at the wavelength of 400 nm was almost zero when adding ≈1.5~2.5% (weight ratio, based on the total weight of PVA and xylan) of TiO2-KH550, which indicated the PVA/xylan composite films were endowed with an excellent UV light shielding ability.

“…Among these particles, the SiC particle was one of the most promising reinforcements due to its superior properties such as good anti-corrosion, a high hardness, satisfied wear resistance, and high chemical stability. Ni-SiC composite coatings have been successfully commercialized in the automotive, aviation, and aerospace industry [10][11][12][13][14], which have been the subject of intensive research for decades.…”

The current work synthesized Ni-SiC composite coating with different SiC microparticle contents. The role of the SiC microparticle in designing the Ni-SiC composite microstructure was revealed. The SiC microparticle physically interrupted the continuous growth of the underlying columnar Ni grains. The columnar Ni grain between the embedded SiC microparticle grew without disturbance. Only upon SiC microparticles was a new layer starting with refined Ni grains observable. The vertical columnar Ni grains reappeared as the position departed the SiC microparticle upper surface. The increase in the contents of the SiC microparticle led to an increased level of grain refinement and the elimination of the (200) fiber texture. Besides that, the number of V-shaped valleys increased as well. Corrosion testing results show that the corrosion resistance of Ni-SiC composite coating increased with the increased SiC contents, which was mainly due to the optimized microstructure.
