This study reveals the internal structure of poly(ethylene glycol) (PEG) network with chain ends crosslinks. PEG networks with different molecular weight and volume fraction were observed by using small-angle neutron scattering and X-ray scattering. The networks exhibited certain domains determined by molecular weight between crosslinks and inhomogeneities influenced by volume fraction. The swollen and cast network also proved the occupation of local domains, consisting of entangled chains or lamellar stacks, in the networks. The results demonstrate the optical properties caused by the localized polymer density in the network, and they provide the ideas to prepare controllable network architecture. |
