Cellulose fiber and nanofibril characteristics in a continuous sono-assisted process for production of TEMPO-oxidized nanofibrillated cellulose

A Novel Highly Conductive, Transparent, and Strong Pure-Cellulose Film from TEMPO-Oxidized Bacterial Cellulose by Increasing Sonication Power

“…However, metal nanoparticles are poisons and nonrenewable materials, which also requires many steps to synthesize in fine quality [ 21 ]. This limitation can be overcome by using ultrasonication [ 22 , 23 ]. By conducting ultrasonication treatment, the tensile strength of the BC powder-based film is increased significantly.…”

Glass-like transparent and heat-sealable films of cellulose nanoworms via ethanol triggered swelling of esterified cellulose

“…Thus, the energy from the collapse of cavities causes ber disintegration. [53][54][55] TEM analysis was performed to reveal more closely the inuence of ultrasonication on the structural alteration of esteried bers, and to determine whether the cellulose was mainly dissolved or formed nanoscale particles (Fig. 2e).…”

Influence of reaction variables on the surface chemistry of cellulose nanofibers derived from palm oil empty fruit bunches

“…23 The differences in reaction yield are caused by the pretreatment process (AHP)-as discussed above-and the mechanical treatment applied to the oxidized material aer the TEMPO reaction, as previously reported. 23,61,62 The ultrasonic probes work within a conned region of the suspension-around the probe tip-where mechanical stress (cavitation) overcomes the cohesive forces between cellulose brils to promote dispersion. 63 As a result, there is some size heterogeneity in the isolated NFCs-represented in the presence of large bers-which were removed during the washing processes.…”
