Abstract
The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension and drying the web in order to form paper or board. According to the invention, the water content of the suspension at the time of beginning of the drying is 50% or less by weight of liquids so as to form a paper or board having an average pore size between 200 and 400 nm. By means of the invention, very opaque paper, for example for printing applications, can be manufactured with low energy consumption.
