Nature always gives us inspirations for fabricating functional materials by mimicking the structure design or stimuli-responsive capability of biomaterials1,2. However, the strict preparation conditions, multi-step processes and high cost of the methods to create biomimetic systems at interface and in bulk, limited their practical applications. Therefore, developing simple, cheap but effective method becomes the focus of our research in this field. The amazing properties of biomaterials are the result of evolution for billions of years. Generally, biomaterials are assembled with limited supply of constitutes available to living organism under mild conditions. The surprising properties of biomaterials are largely resulted from the sophisticated hierarchical structures. Following the design principles of nature to prepare manmade materials has drawn great research interests in materials science and engineering. In the past decades, a large number of papers in this field have been published. In this report, the recent progresses in the preparation of bio-inspired polymers focused on the structure mimicking are summarized3. Selected polymers, such as particles, fiber, interface, bulk and polymer intelligent behaviors from zero to three dimensions, are described with emphasis on the relationship between the structure and the corresponding smart functions.
