apart from aforementioned point surface coupling agent is used for improvement of adhesion. can you suggest some coupling agent for PEEK polymer composite.
Hi,
What kind of reinforcement do you have in mind that you want good adhesion with - carbon fibers?
Coupling agent should be chosen based on both chemistry of fibers and polymer matrix (PEEK in your case).
Cheers,

Hi Bhaskar,
Sorry my mistake, I thought you had matrix with fillers and reinforced with fibers.
Nevertheless, the basic underlying principle stays the same. In order to achieve good adhesion of PEEK with nanofiller particles, you should apply coupling agent on surface of nanofillers. The coupling agent chemically or chemophysically bonds the nanofiller with the polymer matrix. In order to choose this coupling agent you should consider chemistry of both nanoparticles and PEEK.
To suggest a correct coupling agent I must know which nanofiller. Generally, I may suggest to try using y-APS (gamma-APS) silane coupling agent. This one and other silane coupling agents are very popular. Hope this helps
Best Regards,
Andrey
