I have problems when filler was added which expected that the mechanical strenght supposedly be improved but the results show different observation. The filller is usually organic substances that is usually is chemically treated
Depending on the size of the particle, the shape and its aspect ratio (length / diameter) a solid material added to a plastic may or may not act as a reinforcer. Not all fillers can increase the mechanical properties of plastics, in many cases these properties can be deteriorated.
Another important aspect of the aggregate material is its affinity and interaction with the plastic matrix, since this affects the mechanical properties of the final composite material.
Thank you Alcy René Cerón Mosquera Alcy for your answer. I havent check the affinity and interaction with the matrix yet. But, even if i turn the organic filler to the nanocrystal form, it is supposedly have better dispersion on the material but the results of mechanical strenght show differently. What is the problem? if it still happen, that's mean the material doesnt suitable to be a filler right?
Have you check the optimum concentration for your composite? Too much filler will lead to agglomeration and produce composite with weaker mechanical strength. Another suggestion is to check the FTIR of your composite. Do you find any broadening of FTIR band after addition of filler? As this may prove the interaction between filler and your host polymer and evidence of chemical mixing and not only physical mixing.
Thank you Zulhelmi Ismail for your suggesting. I'll check the FTIR to confirm the interaction and get you back.
