Nanofiber having self-heating property and bioactive substance release property, method for producing the same, self-heating property and bioactive substance release functional nonwoven fabric

摘要

The present invention relates to a nanofiber having a self-heating property and a bioactive substance-releasing property that can self-heat and simultaneously release a drug, and can be safely used in the human body without diffusing the self-heating nanoparticles, a method for producing the nanofiber It is an object of the present invention to provide a functional and physiologically active substance releasing functional nonwoven fabric. A fiber having a diameter of 50 nm to 50 μm and a length of 100 times or more of the diameter, and self-heating particles that generate heat in response to an external stimulus, and a physical property that reacts directly or indirectly to the stimulus A fiber in which the physiologically active substance is released to the outside in response to a change in physical properties of the stimulus-responsive polymer. , Its production method and self-heating and bioactive substance release functional nonwoven fabric.
