Progress on the layer-by-layer assembly of multilayered polymer composites: Strategy, structural control and applications

Fiber-Matrix Relationship for Composites Preparation

“…Some researchers have been able to extract nanocellulose crystals with improvement in the modification processes [90]. This includes the bleaching of the alkaline treated fibers and then subjecting them to acid hydrolysis, giving rise to better quality cellulose at the nanoscale [91][92][93][94]. The treatment given to the fibers confirm on them increased rigidity with cleaner surfaces which exposes more of the hydroxyl groups to any further chemical modification [95][96][97].…”

“…These nanoscale cellulose fibers have been reported to lead to improved interfacial interaction [91][92][93][94][96][97][98]. Although, fibers possess hydrophilic properties in nature and polymers are hydrophobic, to improve the interfacial interaction, further chemical modification of the fiber surface may be carried out.…”

Sol-Gel and Layer-by-Layer Coatings for Flame-Retardant Cotton Fabrics: Recent Advances

“…After 10-15 years of significant advances, the LbL method continues to be very well-known and effectively exploited by academic and industrial researchers, as it allows the combination of an almost limitless number of molecularly-sized components bearing different functionalities, permitting the design of tailored assemblies that, despite the very limited thickness, can confer peculiar properties to the underlying substrate without affecting its bulk characteristics [16][17][18].…”

“…Surprisingly, the LbL technique was abandoned until the early 1990s, when a useful methodology for producing nanoarchitectures consisting of layers of anionic and cationic polyelectrolytes on a substrate was proposed [15]. As a result, assembly deposited on fabrics does not affect their bulk mechanical behavior, providing, at the same time, useful features that are strictly dependent on the type and number of deposited layers [16][17][18].…”

Crystallization behavior and optical properties of isotactic polypropylene filled with α-nucleating agents of multilayered distribution

“…Particularly, the emergence of layer-multiplying co-extrusion technology, which can enable the construction of multilayered structure to be more efficient and controllable, brings mass enthusiasm for developing superior properties via multilayered distribution of llers. 21 Many reports have stated that multilayered distribution of llers exhibited more efficient for modication compared with the random state, that has been applied to prepare composites with outstanding mechanical, electrical, dielectric, barrier, and optical performances. [22][23][24][25][26][27][28][29] However, few studies focusing on the relationship between multilayered distribution of a-NAs and optical properties of iPP are concerned, as far as we know.…”
