A surface functionalizing method for use in high-throughput in situ synthesis of nucleic acids by 3D inkjet printing. The method includes subjecting a surface of a substrate to hydroxyl enrichment treatment; adding hydrophobic molecules to the surface of the substrate, the hydrophobic molecules being not reactive with phosphoramidite monomers; spraying, by a multi-channel piezoelectric inkjet head assembly, an etching ink to a predetermined area on the surface of the substrate for micro-etching, the etching ink being prepared with a fluoride compound reactive with the hydrophobic molecules; and adding hydrophilic molecules to the surface of the substrate. By using the method, a functionalized surface with given areas being patterned can be formed on the surface of the substrate, and then a same multi-channel piezoelectric inkjet head assembly can be directly used for subsequent high-resolution printing of phosphoramidite monomers and synthesis of nucleic acids.

A porous filler for reducing the gas permeability of an elastomer composition, a process for producing the elastomer composition comprising the porous filler, and the elastomer composition itself. The porous filler is selected from surface-reacted calcium carbonate, precipitated hydromagnesite and mixtures thereof. The addition of the porous filler to the elastomer composition allows for reducing the gas permeability of the elastomer composition while retaining or improving the mechanical properties of the elastomer composition.
