Abstract:
The present invention relates to ultrafine fiber-based composites comprising at least one ultrafine fiber-type hydrophobic polymer and oxide moisture absorbent particles distributed on the polymer. The ultrafine fiber-based composites may be appropriately used as sealing materials which can prevent the functional deterioration of electric or electronic devices and enhance the stability due to their high hydroscopicity and ability to maintain their appearance without change after the absorption of moisture.
