Good day to all. I need advice on preparing nano zirconia in polymer. After inside the zirconium precursor with acetone,water and acid, I cast my mixture but then in few day I notice that white solid layer on the bottom. I think my zirconia not mix with my polymer. If i prepare silica as the filler with the same procedure, the end dried sample is completely homogenize. Kindly need advice on this matter.Your attention and comments are highly appreciated.
Thank you
Your question is not clear and can you tell us a little background. What Zr precursor are you using? In your case, you may not not forming ZrO2, instead you might have hydrated Zr (i.e. Zr(OH)4). You need to reduce it to ZrO2, then mix with polymer.
There are four techniques usually to prepare nanocomposite material. The one you did as I believe is mixing the polymer with precursor and in-situ precipitation was carried out. I think while in a process of in-situ precipitation, you may need to put the mixture into a homogenizer with continuous stirring for specific period of time, until the results show you better homogenization of your filler.
Greeting Mr. Abdulmenan Hussein.
For your information, Zr precursor that I'am using is zicronium (IV) propoxide. I add 10% of this precursor in my polymer matrix. Your advice is highly appreciated.
