In this paper, we report our attempt to elaborate on cellulose-based materials and their potential application in membrane science, especially in separation applications. Furthermore, the cellulosic membrane has received attention for potential use as biomaterials such as novel wound-dressings and hemodialysis materials. In this mini-review, we mainly focus on the separation and antimicrobial properties of cellulosic membranes and the advanced synthesis/processing methods for superior functional quality for various potential applications. Finally, we conclude with the market and the impact of developments of future expectations.

Larviciding is an effective control method in managing mosquito-borne diseases. However, current carrier materials used in larvicides formulation raised environmental concerns due to its non-renewable origin. Herein, our study aimed to evaluate the application of the renewable source kenaf cellulose nanofiber (KCNF) impregnated with temephos for the control of Aedes aegypti mosquito larvae. The morphology of KCNF+T was examined using field emission scanning electron microscope (FESEM) and transmission electron microscopy (TEM) while the quantity of temephos impregnated, released, and retained on the fibers upon dispersion in water were determined using high performance liquid chromatography (HPLC). Subsequently, the bioefficacy of the KCNF+T was evaluated against Ae. aegypti larvae. The FESEM and TEM micrograph verified the presence of temephos on the KCNF after the impregnation. HPLC analysis showed the amount of temephos impregnated on KCNF was 97 % of the 0.1 mg temephos. Upon dispersion in water, KCNF+T released 53% temephos and the retention of temephos on KCNF+T gradually decreased to 30, 17 and 7 % on the first, third and fifth month, respectively. The exposure of Ae. aegypti larvae to KCNF+T at concentration 0.006 to 0.01 mg/L was effective at 17 - 25 folds in killing Ae. aegypti larvae compared to temephos without KCNF. Microscopy examination revealed accumulation of the KCNF on the larval appendages. Overall, our study demonstrated that KCNF made from renewable source is an effective nanocarrier of temephos for the control of Ae. aegypti mosquito larvae.

The need for new sustainable engineering materials using polymer composites is evolving every day. Researchers are in a race to develop value‐added products from natural renewable sources and discarded waste materials. Studies indicate several hurdles while trying to provide ecologically friendly materials for product manufacturing over the years. Natural materials are more readily available, biodegradable, more affordable, have less processing health hazards, and are more environmentally friendly than synthetic materials. As the price of commercial polymers decreased, the incorporation of fillers became increasingly necessary for technical reasons.. The market for polymers can actually be expanded by appropriately combining fillers and polymers to produce a wide range of qualities in these two components. This review provides an overview on a variety of organic and inorganic fillers which were incorporated into the polymer composites and their influence on the physical, chemical, mechanical, thermal, and electrical properties of polymer composites by various characterization methods and their In fact, it is possible to achieve a wide range of qualities in these two components by appropriately combining polymers and fillers, which expands the market for which polymers may be employed.application scopes. This review aims to thoroughly examine and assess various polymer and filler combinations, with a particular emphasis on their potential suitability for a range of engineering and industrial applications. These encompass microelectronics, biomedical fields, flexible electronics, flame retardant uses, food packaging, automotive and aerospace sectors, as well as applications within the construction industry for structural and semi‐structural purposes.Highlights New polymer composite engineering materials with long‐term sustainability Value‐added product development from renewable resources and discarded waste materials. Provide information to select appropriate reinforcements for composite manufacturing. Diverse discussion on the application of fillers and their composites.
