Foamed material and method for preparing same

Abstract

The present invention relates to the technical field of biodegradable materials, and in particular, to a novel foamed material, a method for preparing same, and use thereof. The foamed material at least comprises a crystalline PHA and an amorphous PHA. The foamed material prepared by the present invention features good foaming performance. It improves the poor thermal stability, narrow processing window, low crystallization rate, and high fragility of PHA materials while retaining the original advantages and performances of the PHA materials. Therefore, the foamed material of the present invention can meet the requirements for biodegradability and certain cushion performance in applications such as high-tech appliances, packaging materials of electronic equipment, sports shoe sole materials, carpet materials, soft package materials of automotive interiors, sewage treatment materials, medical microporous foamed materials, and the like.
