Searching for entanglement tube dilation in all-polymer nano-composites: linear chains with stars
Recently, a spectacular entanglement tube dilation of linear polymer chains has been observed by NSE on a nano-composite with single-chain polymer nano-particles (SCNPs). This effect was attributed to indirect confinement effects produced by compression of the linear chains close to interfaces with the SCNPs. Such compression was corroborated by SANS measurements on the nano-composite. It was argued that the special topology of SCNPs leading to an enhanced amount of interfaces would magnify the impact of the presence of NPs on the linear chains behavior. Here we aim to check whether chain contraction and subsequent tube dilation are also present in linear chains under the presence of star polymers, which shall also provide a great amount of interfaces in the mixture.
