| 英文摘要 | In this study, porous thermoplastic polyurethane (TPU) micro-films were fabricated using a novel diffusion restricted foaming technology. TPU film with thickness of 40?50 ?m was sandwiched between two polyimide (PI) films by hot compression. Porous TPU films with tunable cell morphology were obtained by manipulating interface bonding force, gas solubility, and driving force for cell growth. The sandwiched PI films could act as a gas barrier film to trigger the enhanced interface cell nucleation, resulting in skin-free cellular TPU film and oriented internal microcellular structure. The possible mechanism of microvoid-assisted interfacial cell nucleation and the preferential cell growth along the thickness direction was proposed with aim to explain the cell morphology and their evolution. |
