The equilibrium phase behavior of 43 linear poly(isoprene-b-styrene-b- ethylene oxide) (ISO) triblock copolymer melts, with molecular weights that place these materials near the order-disorder transition, is reported. Ordered phase morphologies were characterized using small-angle X-ray scattering, transmission electron microscopy, dynamic mechanical spectroscopy, and static birefringence measurements. Interpretation of these results was aided by a modeling technique that facilitates resolution of reciprocal and real-space experimental data, leading to definitive three-dimensional morphological structures. Three distinct multiply continuous network morphologies are identified across a range of compositions between 0.1 ≤ f o ≤ 0.3, situated between two-domain and three-domain lamellae, where f o …

The self-assembly of functionalized inorganic nanoscale building blocks (NBB) was investigated using recognitive biomolecule linkers. The NBBs and linkers were studied using bond fluctuation model and algorithm on a simple cubic lattices. The loops contained in the soluble material to avoid double counting when calculating the fraction of loops. The algorithm was used to calculate additional network properties when volume fractions above the percolation threshold was simulated.
