Incomparable hardness and modulus of biomimetic porous polyurethane films prepared by directional melt crystallization of a solvent

Freeze casting – A review of processing, microstructure and properties via the open data repository, FreezeCasting.net

“…2. Demonstrated solidification heights for this configuration range from 100 μm [180], using a combined doctor-blade/freeze-casting technique, to 9 cm [181] via traditional methods as described above. Sample areas as large as 38 x 15 cm [182] have been demonstrated via unidirectional freeze-tape-casting [182][183][184][185][186][187][188].…”

“…Lastly, the dendritic structure shown in Fig. 11(c) is a polyurethane material templated using dioxane [180]; the precursor was also a solution.…”

“…N R 2 (180), SiAlON (800), CaSiO 3 (100), whereas literature values were taken for: Y 2 SiO 5 (116 [891]), ZrB 2 (300 [892]), lead zirconate titanate (PZT; 90 [893]), Yb 2 SiO 5 (150 [894]), Ca 3 ZrSiO 9 (98 [895]), and mullite (240 [507]). Rule of mixtures, using the aforementioned values, was used to approximate values for mixed particle systems.…”

Synthesis and Characterization of Polyether Polyol Based on Epoxy Cyclohexane and Epichlorohydrin

“…They are widely used in construction and decoration industry, textile industry, automotive industry, aerospace materials and other aspects of the people's livelihood [5]. With the increasing consumption of polyurethane products, the demand for polyether polyols increases year by year [6].…”
