Biobased sustainable materials made from starch and plasma/ultrasound modified Agave fibers: Structural and water barrier performance

Biopolymer composites based on ultrasound/plasma‐modified fiber waste and polybutylene adipate terephthalate (PBAT): Physicochemical and functional performance

“…17 Moreover, a hydrophobic HMDSO coating could be deposited on the fiber surface after plasma treatment, improving their compatibility with the PBAT matrix. 16 Similar behavior has been reported for LDPE composites containing HMDSO-functionalized cellulose fibers since the higher dispersion of the modified fiber in the matrix resulted in stronger fiber-matrix interaction. 19 Table 1 presents the processing parameters as the required energy to manufacture the PBAT-AF blends, which were estimated using the peak end-load peak divided by sample mass.…”

“…[12][13][14] Dual treatments like cold plasma and ultrasound are alternative physical treatments that change the structural properties of Agave fibers from hydrophilic to hydrophobic since the treatments alter the structure of the lignocellulosic components, reducing moisture absorption. 15,16 Furthermore, their effect on the functional properties of starch-based films has been inspected, finding that the ultrasound/plasma-modified AF improved the mechanical interlocking and water barrier performance of the films. 17 Nevertheless, the effect of these modified AF has only been explored in a starch matrix at the laboratory level using the casting method, and there is no current evidence of their performance at the pilot plant scale with a hydrophobic degradable matrix.…”

Effect of Low-Temperature Plasma Treatment on Starch-Based Biochar and Its Reinforcement for Three-Dimensional Printed Polypropylene Biocomposites

“…Plasma modification techniques drastically shorten processing times and reagent requirements, excluding functionality relevant to the surface. The method of plasma functionalization is adaptable, quick, and clean. , The slower chemical reactions with the chemically active species happen exclusively on the surface of the carbon material during plasma operations; they do not affect the bulk properties at low atmospheres with protracted application times. By using various gas sources in plasma processes, acidic and basic functional groups can be introduced on the surface of carbon-based materials. − Excited molecules and radicals react with surface-bound carbon double bonds during plasma interactions to provide open ends and imperfect sites for functionalization.…”
