Embodiment Construction
[0027] A method for hydrophilic modification of a hydrophobic macromolecule microporous carrier, comprising the steps of:
[0028] 1) cleaning the injection molded part of the hydrophobic polymer trace porous carrier;
[0029] 2) Place the cleaned injection molded part in the generation cavity of the radio frequency plasma generator for surface modification treatment;
[0030] 3) Soak the surface-modified injection molded part in a hydrophilic modification enhancement solution;
[0031] 4) Take out the injection molded part after soaking treatment, drain and dry to obtain the injection molded part of hydrophilic trace porous carrier.
[0032] As a further improvement of the above-mentioned hydrophilic modification method, the hydrophilic modification enhancement liquid is an aqueous solution containing chloroform, polyvinyl alcohol 205 and sodium carboxymethyl cellulose, and the mass concentration ratio of the three components is 3:(1 ~2.5): (1~3), and the total mass concent...
