Abstract Nanofibrillated cellulose (NFC) was systematically tailored by ultrasonic-assisted esterification with lactic acid at different amplitudes and times, which led to modified NFC (mNFC) with different degrees of substitution (DS), between 0.21 and 0.55, as confirmed by titration, FTIR, and C13 NMR. A partial fragmentation and decrease in crystallinity of mNFC were revealed by TEM and XRD. To

Largely enhanced dielectric properties of TiO2-nanorods/poly(vinylidene fluoride) nanocomposites driven by enhanced interfacial areas Nanocomposites (IF 4.6) Pub Date : 2021-07-23 Pornsawan Kum-onsa, Narong Chanlek, Prasit Thongbai
Abstract In this work, nanocomposites consisting of TiO2-nanorods (TiO2-NRs) with less than 100 nm in size and poly(vinylidene fluoride) (PVDF) were prepared using a liquid-phase assisted dispersion and hot-pressing methods. At 1 kHz and 25 °C, the high dielectric permittivity of ∼66 and loss tangent of ∼0.03 can be obtained in the nanocomposite with a filler volume fraction of 0.5, which was higher

The investigation of reinforcement properties of nano-CaCO3 synthesized from Achatina fulica snail shell through mechanochemical methods on epoxy nanocomposites Nanocomposites (IF 4.6) Pub Date : 2021-06-18 O. J. Gbadeyan, S. Adali, G. Bright, B. Sithole
Abstract The current study investigates the reinforcement properties of novel nano-calcium carbonate (nano-CaCO3) synthesized from Achatina fulica snail shell. The shell was wet-milled to nanoparticle sizes using mechanochemical procedures. Epoxy nanocomposites prepared with nanofiller content ranges of 1–7 wt.% were fabricated using a conventional resin casting method. Thermal stability and degradation

Silane compatibilzation to improve the dispersion, thermal and mechancial properties of cellulose nanocrystals in poly (ethylene oxide) Nanocomposites (IF 4.6) Pub Date : 2021-07-10 Saptaparni Chanda, Dilpreet S. Bajwa, Greg A. Holt, Nicole Stark, Sreekala G. Bajwa, Mohiuddin Quadir
Abstract Cellulose nanocrystal (CNC) has potential to be used as a reinforcement in polymeric nanocomposites because of their inherent biodegradability, universal accessibility, and superior mechanical properties. The most crucial challenge faced in the nanocomposite production is dispersing the nanoparticles effectively in the polymer matrix, so that the exceptional mechanical properties of the nanoparticles

The effect of deposition angle on morphology and diameter of electrospun TiO2/PVP nanofibers Nanocomposites (IF 4.6) Pub Date : 2021-05-25 Nabeel Z. Al-Hazeem, Naser M. Ahmed, M. Z. Mat Jafri, Asmiet Ramizy
Abstract Electrospinning has become a robust technique for the cost-effective production of fibrous materials. In a conventional electrospinning process, the produced fibers are fabricated by either vertical or horizontal setups, resulting in isotropic non-woven fibers mats. Many researchers have focused on the influence of various electrospinning parameters, solution parameters and ambient parameters
