发帖数: 741 | 1 I recently coated a PTFE (poly tetra fluoro ethylene) device with some
methacrylat. The coating layer gave round disk like uncontinued morphology
on the device surface, we need get even surface.
I used simple coat method, dip the device into the mehacrylate monomer/
initiator solution, take it out and let the monomer polymerize on the device
surface.
Any suggestions? Thanks in advance, do you think spin coating would help? or
any other coating method? |

learn the techniques you mentioned? |

the polymer MW is controllable. Then spray the polymer solution on the
surface of PTFE and evaporate the solvent. |

发帖数: 133 | 5 coat sth onto PTFE is technically difficult due to the surface tension of
PTFE.
physical/chemical etching is necessary according to published articles. |
