Abstract
Provided is a poly-p-xylyene having at least one chemically active functional group present in a form of particles. In an embodiment, the functionalized poly-p-xylylene is synthesized via CVD, and electrospinning is then performed at a relatively low polymer concentration, so as to produce functionalized poly-p-xylylene particles. The functionalized poly-p-xylyene particles have a particle size at nano-scale or micro-scale. Such functionalized poly-p-xylyene particles can be applied to biological fields extensively.
Claims19
A polymer particle, comprising:
- a poly-p-xylyene having at least one chemically active functional group in particle form, wherein the poly-p-xylyene has a particle size at nano-scale or micro-scale.
A preparation method of a polymer particle, comprising:
- dissolving a poly-p-xylyene thin film having at least one chemically active functional group in a solvent to form a polymer solution;
- and
- spraying the polymer solution on a collection plate via an electrostatic spraying method to obtain a poly-p-xylyene particle having the chemically active functional group on the collection plate.
