Marine sponge melanin: a new source of an old biopolymer
2011年8月7日 · The possibility that marine sponges could integrate this large group of melanin-producing organisms arises from the observation of a dark pigmentation (mostly black, brown or grey) at the surface of several sponge species in their natural habitats.
Melanin pigment derived from marine organisms and its industrial ...
2022年5月1日 · Melanin is a complex group of natural pigment substance, and it shows excellent biological and biomedical applications which is commonly present in algae, fungi, bacteria, cephalopoda, and sea cucumber.
Marine sponge melanin: A new source of an old biopolymer
2012年2月1日 · Various types of melanin have already been found in the majority of organisms, being this biopolymer considered as one of the major pigments present in nature. The presence of this pigment in...
A Durable Magnetic Superhydrophobic Melamine Sponge: For …
This magnetic effect enables sponges to be driven by magnets in practical applications, changing the direction of movement of sponges to absorb oil in different containing areas, thereby improving sponges’ practicality and adsorption efficiency.
An environmentally friendly and superhydrophobic melamine sponge …
In this work, a new environmentally friendly and superhydrophobic melamine sponge for oil-water separation was successfully prepared by facile self-polymerization of dopamine followed by grafting of octadecyl amine on the sponge surface.
Engineering Lignin Nanoparticles Deposition on Melamine Sponge …
2019年7月29日 · Here, we fabricate two highly hydrophobic melamine sponges with excellent adsorption performance and flame retardancy through a facile spontaneous deposition of lignin and/or acetylated lignin nanoparticles onto the MF sponge skeleton.
Superhydrophobic melamine sponges with high performance in …
2023年10月1日 · The superhydrophobic sponge exhibited excellent sorption capacities up to 160 times its own mass, good recyclability with retention of over 93% after 50 sorption/squeezing cycles, exceptional stability under harsh conditions, superb selectivity enabling continuous oil/water separation and outstanding demulsification ability, which is among the ...
Durable, magnetic-responsive melamine sponge composite for …
2021年4月14日 · The prepared melamine sponge composite (PTOS-Fe 3 O 4 @PDA/MF) not only exhibits a very high water contact angle of 165 ± 1.5° and an excellent ability to uptake a variety of oils and organic solvents (e.g. up to 141.1 g/g for chloroform), but also shows robust durability and superior recyclability.
A graphene–melamine-sponge for efficient and recyclable dye …
In the present study, we developed a graphene–melamine-sponge (GMS) that can readily submerge into water solution with the help of a superhydrophilic melamine skeleton and investigated its adsorption behaviors for methylene blue (MB) and orange G (OG). The obtained GMS efficiently adsorbed methylene blue with competitive capacity.
In this study, superhy-drophobic melamine sponges (SMSs) with the above characteristics were pre-pared by modifying melamine sponges with polymethylsilsesquioxane via an immersion method. A villiform layer of organosilane was coated on the surface of the melamine fibers and disclosed by scanning electron microscopy.
