| titleOfInvention | Ordered porous structure material based on common crystalline polymer and preparation method thereof |
| abstract | The invention provides an ordered porous structure material based on a common crystalline polymer and a preparation method thereof, belonging to the technical field of the preparation of ordered porous structure materials. In the method, a composite seed having an affinity for polyvinylidene fluoride is used to protect the high-energy crystal face of polyvinylidene fluoride, reducing the crystal face can prevent disordered aggregation and make the crystal develop along one-dimensional direction. The invention utilizes the special affinity between the composite seed crystal and the polyvinylidene fluoride incompletely fluorinated molecular chain to realize the control of the polyvinylidene fluoride molecular conformation during molding, thereby controlling the molecular chain folding and aggregation mode during crystallization. The method can control the number of nucleated polyvinylidene fluoride, and utilize the steric hindrance of the seed crystal and the protection of specific crystal planes to obtain high-energy crystal planes of directional aggregation, combined with the interface effect and shear effect in the molding process of the product, Thus, the directional assembly of the polyvinylidene fluoride crystal planes is obtained, and a porous polyvinylidene fluoride polymer material product composed of ordered nanofiber crystals is formed. |
