Article Synopsis
- The surface properties of polymer blends can be influenced by the presence of shorter chain components, which can affect their performance in specific applications.
- Observations using a technique called SL-MALDI-ToF-MS revealed that even polymers that seem to have uniform molecular weight show a tendency for shorter chains to accumulate at the surface.
- For instance, 6 kDa polystyrene has a surface molecular weight about 300 Da lower than its bulk counterpart, while 7 kDa poly(methyl methacrylate) shows a shift of around 500 Da, aligning with predictions from mean-field theory.
