“…The kapok fibers kept their porous form in all CTAB doses tested, indicating that the top kapok layer area was not reduced. These findings definitely suggest that CTAB has a substantial role in distributing PAN atoms throughout the kapok fiber top layer [106]. Although raw fiber is compared to surface-coated fiber, the rough surface with low surface energy efficiently prevents oil from flowing from the fiber structure, leading to a high oil sorption rate.…”

The increasing degradation of fossil fuels has motivated the globe to turn to green energy solutions such as biofuel in order to minimize the entire reliance on fossil fuels. Green renewable resources have grown in popularity in recent years as a result of the advancement of environmental technology solutions. Kapok fiber is a sort of cellulosic fiber derived from kapok tree seeds (Ceiba pentandra). Kapok Fiber, as a bio-template, offers the best alternatives to provide clean and renewable energy sources. The unique structure, good conductivity, and excellent physical properties exhibited by kapok fiber nominate it as a highly favored cocatalyst for deriving solar energy processes. This review will explore the role and recent developments of KF in energy production, including hydrogen and CO2 reduction. Moreover, this work summarized the potential of kapok fiber in environmental applications, including adsorption and degradation. The future contribution and concerns are highlighted in order to provide perspective on the future advancement of kapok fiber.

“…Agcaoili et al. have found that by coating kapok microtubes with polyacrylonitrile, high adsorption capacities for methylorange (34.72 mg g −1 ) and copper (90.09 mg g −1 ) can be achieved . With a proper functionalization, kapok fiber can show excellent properties for the removal of heavy metal ions like copper from aqueous solution.…”

As the most abundant natural polymer, cellulose presents a unique advantage for large-scale applications. To fully unlock its potential, the introduction of desired functional groups onto the cellulose backbone is required, which can be realized by either chemical bonding or physical surface interactions. This review gives an overview of the chemistry behind the state-of-the-art functionalization methods (e.g., oxidation, esterification, grafting) for cellulose in its various forms, from nanocrystals to bacterial cellulose. The existing and foreseeable applications of the obtained products are presented in detail, spanning from water purification and antibacterial action, to sensing, energy harvesting, and catalysis. A special emphasis is put on the interactions of functionalized cellulose with heavy metals, focusing on copper as a prime example. For the latter, its toxicity can either have a harmful influence on aquatic life, or it can be conveniently employed for microbial disinfection. The reader is further introduced to recent sensing technologies based on functionalized cellulose, which are becoming crucial for the near future especially with the emergence of the internet of things. By revealing the potential of water filters and conductive clothing for mass implementation, the near future of cellulose-based technologies is also discussed.not suitable for drinking water treatment in rural areas or not applicable on a large scale. Other methods involving materials which have high adsorption capacities for pollutants, for example activated charcoal have been explored. [27,28] Nevertheless, there are no universal adsorbents for all pollutants, meaning that superior alternatives are still required. In recent years, biodegradable adsorbents such as cellulose and chitosan have attracted much attention for the removal of heavy metals.In particular cellulose has a number of advantages, which include high abundance, low cost, easy access, nontoxicity and biodegradability. It is particularly suited for the removal of low concentrations of heavy metals which occur in contaminated ground or tap water. [26] Beyond the aspects of copper removal from water, in this review we indicate how the metal's increased toxicity for microbial life can present an advantage for medical applications. Moreover, we also take a closer look at further applications of functionalized cellulose, including catalysis and sensing, which can make a great impact regarding energy conversion and management. The inclusion of conductive cellulose sensors within the internet of things global network is of particular interest, since an accurate weather forecast can provide swift adjustments in the usage of the often intermittent renewable energy sources. In order to understand what confers functionalized cellulose its versatility for broad applications, we first exemplify the functionalization techniques on a molecular basis.
