The present invention relates to a method for manufacturing structural layers for guiding liquid flow on a porous substrate, by printing onto at least one area of at least one surface of the substrate a printing solution containing an aqueous dispersion of a poly(lactic acid)-based copolymer.

Liquid guiding boundaries for porous substrates providing increased biodegradability

According to an example aspect of the present invention, there is provided bio-based mineral oil barrier coatings and films usable for decreasing mineral oil migration, for example in food packaging materials, and thus improving the safety of the materials facing the mineral oil containing environment.

Bio-based mineral oil barrier coatings and films

The present disclosure relates to a method for manufacturing a covalently functionalized coated magnetic nanoparticle and to said particles and uses thereof. The preparation method includes forming a shell of a hydrophilic polymer coating layer on top of a magnetic metal core coated with a carbon coating. In the method a particle comprising a magnetic metal core coated with a carbon coating is provided. The surface of the particle is subjected to covalent functionalization by generating amino reactive groups via diazonium chemistry and subsequently an irreversible attachment of an atom transfer radical polymerization (ATRP) initiator is carried out on said surface. A hydrophilic polymer layer is formed) by a surface initiated atom transfer radical polymerization (SI-ATRP) reaction with a monomer comprising N-isopropylacrylamide (NIPAM).
