Background. As a hydrophilic compound, alginate needs to be modified perform both as an emulsifier and matrix for fish oil encapsulation. Dodecenyl succinic anhydride (DSA) was selected the modification due its mild reaction conditions fact that no side product is generated. The purposes of this research were prepare partial hydrophobic groups alginate, which subsequently used encapsulant. Mate...

In this study, silicone rubber and oil were used to modify melamine sponge obtain lipophilic hydrophobic properties. The result showed that the modification had no effect on intrinsic properties of sponges such as structure elasticity. After modification, changed from hydrophilic superhydrophobic, contact angle could reach 155.7°. addition, also maintained its good oil-absorption performance ex...

The amphiphilic graft copolymer using chitosan (CS) as hydrophilic segment and poly (L-lactic acid) (PLLA) as hydrophobic segment, was prepared through a protection-graft-de protection route. Chitosan is a polysaccharide comprising of copolymers of glucosamine and N-acetyl glucosamine. Chitosan is the deacetylated derivative of chitin, which is one of the most abundant natural polysaccharides c...
