Title: Dynamically covalently cross-linked cellulose-based bioplastic, wood-plastic composite material, preparation method therefor, and use thereof
Inventor: WANG XIAOHUI
IPC: C08J3/24
Filed: 2020-04-17
Abstract: The present invention belongs to the field of material chemistry, and specifically discloses a dynamically covalently cross-linked cellulose-based bioplastic, a wood-plastic composite material, and a preparation method therefor. Said method reconstructs a hydrogen bond network between cellulose molecular chains into a dynamic covalent bond link network, thereby preparing a cellulose-based bio-based plastic that is heat-processable, has a high strength and a high modulus, and is degradable and recyclable. Compared with most existing cellulose-based materials linked by hydrogen bonds, the cellulose-based bioplastic prepared by the present invention is cross-linked by dynamic covalent bonds, which enables the cellulose-based plastic to have excellent reprocessing, thermal processing and degradable properties. In addition, because interface compatibility can be improved by means of hydrogen bond interaction between the two phases, the present novel wood-plastic composite material prepared from cellulose- and bio-based plastic and biomass has higher tensile strength and a higher Young's modulus.

Abstract: A hybrid matching approach can be used for computer vision that balances accuracy with speed and resource consumption. Stereoscopic image data can be rectified and downsampled, then analyzed using a semi-global matching (SGM) process. The use of downsampled images greatly reduces time and bandwidth requirements, while providing high accuracy disparity results. These disparity results can be provided as external hints to a fast module that can perform a robust matching process in the time needed for applications such as real time navigation. The external hints can be used, along with potentially other hints, to define a search space for use by the fast module, which can result in higher quality disparity results obtained within specified timing constraints and with limited resources. The disparity results can be used to determine distances to various objects, as may be important for vehicle navigation or robotic task performance.
