A new class of green material has been elaborated by grafting the modified kapok fiber, by the means of azidated kapok fiber followed by "click-chemistry" reaction with the terminal alkyne crosslinker. The modified and synthesized product was characterized using Fourier transform infrared spectroscopy (FT-IR), and Scanning electron microscopy (SEM). The study also was undertaken to investigate the effect on the absorption of methylene blue from aqueous solution onto the click fiber prepared. The findings showed that the click kapok absorbed more compared to the untreated kapok. Based on the result, the reaction of click chemistry influenced the properties of the filter made from kapok fiber.
Calcium hydroxide filler dispersions, of various particle sizes, were prepared by mixing sodium hydroxide with calcium chloride, in various concentrations, at room temperature. The resulting filler dispersions were added, in various amounts, to the banana stem mechanical pulp, which was then converted to handsheets. Increasing the filler loading increased the tensile index but reduced the tear index and water absorption of the handsheets. The SEM micrographs of the handsheets surfaces and the tensile fractured surfaces of the handsheets tensile test specimens showed that increasing the filler loading resulted in the formation of more and bigger filler aggregates in the spaces between the fibre. The filler particle size did not have any significant effect on the handsheets properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
