Abstract
A super-wet surface is a polypropylene surface, on which a hydrophilic side group is grafted, having a micro-nano structure. The super-wet surface is at least super-hydrophilic and does not contain an initiator residue. The super-wet surface is prepared by grafting, in the absence of an initiator, by means of microwave irradiation, a monomer for forming a side group, on the polypropylene surface, as a grafting base, having a micro-nano structure. In the preparation of the super-wet surface, the molecular weight of polypropylene does not decrease after grafting, there is no residual monomer or initiator residue, and the super-wetting effect of the obtained surface is lasting and stable. The super-wet surface can be used in bonding, spraying, oil-water separation, water treatment, biology, medicine and energy fields.
