摘要:
The invention relates to a new ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a surface of a solid substrate having compounds of the general formula A-B in which A is a group having the formula (I) in which Z is C or N+; X is C-H or C-L, wherein L is an electroattractive group chosen from F, CF3, NO2 and N(CH3)3+; Y is H or CH3, or Y, together with X, forms a heterocycle of 5 or 6 atoms; T is NH, CO, CONH or NH2+U-, wherein U- is a soluble anion, and B is a C1-C20 aliphatic linear alkyl group replaced partially or completely by F. The invention also relates to a method for preparing said layer and its use as a barrier film.
摘要:
wherein A is an at least monosubstituted alkylene or arylene group; B is an amide, ester or ether group and n is 0 or 1; F is selected from: an ester, secondary amine, amide, ether, thio ether, thio ester, and may be the same or different for the different side chains; D is a side chain intended to reversible bind to a substrate or has a coating function; E is a side chain intended to irreversible bind to a substrate, the side chain E and polymer includes 1 to 10 different side chains D and 1 to 10 different side chains E, but at least one of each, and includes a plurality of each type, whereby the different types of side chains are randomly or regularly distributed in the polymer.

摘要:
The present invention provides a functionalized macromolecule and a composition comprising said functionalized macromolecule, which is suitable for use as an adhesion promoter. The functionalized macromolecule comprises a polymeric core, which comprises a natural, semi-synthetic or synthetic polymer, and at least two functionalized side chains, which are linked to the polymeric core by a linker group. The functionalized side chains comprise a photoreactive group.
