“…The popularity of these crossbreed types of composites is increasing rapidly owning to their capability to provide freedom to tailor the composites and achieving properties that cannot be acquired in composite encompassing only one kind of material [13,144]. One of the major reasons for creating crossbreed NFPCs is to utilize the pluses of the fibers and lessen some drawbacks [145].…”

Fiber-matrix interaction at the interphase is one very important property that is of great concern to all polymer scientists involved in polymer composites. Many of the failures can be traced to the type of interfacial interaction existing in the composites. That is why highlighting the factors that dictate the type of and the extent of interactions at the interphases become very necessary. Natural fiber polymer composites have found application in many fields of human endeavors. To continue this growth being experienced, the factors that determine the formation of good interaction at the interphase most be understood, so that they can be manipulated for a better result.

“…This method requests the use 2-propanol as an external solvent. In addition, post-sulfonation of CNFs has also been conducted using hazardous chlorosulfonic acid (Luo et al 2018). In case of post-sulfonation, anhydrous condition were used together with dimethylformamide as a solvent.…”

“…During the various treatment processes, such as oxidation through 2,2,6,6‐tetrametyl‐1‐piperidinyloxy (TEMPO) method or sulfonation by using periodate and bisulfite, the surfaces of CNFs become more negatively charged, owing to the presence of carboxylic acid groups or sulfate ester groups . The electrostatic repulsion between negatively charged CNFs benefits good dispersion and stability in the aqueous phase . CNCs, also known as nanocrystalline cellulose or cellulose whiskers, are typically generated by strong acid hydrolysis of cellulosic fibers by using sulfuric or hydrochloric acid.…”

Nanocelluloses (NCs) have remarkable mechanical properties and contain abundant surface functional groups that can be modified or cross‐linked with other materials. They have been widely used as an environment‐friendly reinforcing agent in polymer composites. However, for applications that are carried out in humid environments or aqueous suspensions, hydrophilicity of NCs lower their mechanical integrity. Hence, cross‐linking techniques have been investigated in recent years for preparing NC‐based materials that are dimensionally stable under humid or aqueous environments and have better physicochemical properties. This Minireview examines the quickly growing field of cross‐linked NC‐based materials, which have many benefits including improved aqueous, structural, mechanical, and thermal stability. In addition, the potential application of cross‐linked NC‐based materials in adsorption of heavy metal is discussed.
