Generation of hydrophobic surfaces on paper - A new moisture barrier for fibrous materials?
Fibres represent the majority of the packaging materials used. They are based on renewable raw materials and are very easy to recycle. However, they are very hydrophilic, which is why a plastic coating is necessary for some applications. Two simple methods for plastic-free coating of a paper material have been developed. The paper surface becomes superhydrophobic (contact angle approx. 150°) and shows very low rolling angles.
