Green One-Step Modification of Spent Coffee Grounds and Their Application as Novel Bio-Based Flame Retardant in Waterborne Epoxy Resin

Danqi Wu Mengmeng Yang Tinghao Wu Tingwei Wang Yucai Shen

Fire retardant coatings are moving towards environmentally friendly products, and the development of green flame retardants is gradually attracting the attention of researchers. In this work, spent coffee grounds (SCG) were modified with m-xylylenediamine phosphate ammonium (MAP) to create a bio-based flame retardant (SCG-g-MAP) for waterborne epoxy resin (WEP). The structure and composition of SCG-g-MAP were analyzed by a range of characterization tests, and the effects of SCG-g-MAP on the thermal stability, flame retardancy and fire resistance of WEP composite coatings were discussed. It revealed that WEP composite coating with 10% SCG-g-MAP and partial conventional intumescent fire retardant fillers, resulted in a LOI value of 29.5% and self-extinguishing capability. Moreover, the coating exhibited significantly improved fire resistance and thermal insulation properties due to its better thermal stability and excellent barrier function of forming carbon layer. This work presents a new attempt and inspiration for the application of biomass waste such as SCG for green flame retardant fillers.

Constructing integrated thermal conductive and flame-retardant filler network in ceramifiable epoxy composites

Journal of Reinforced Plastics and Composites (2023)

Lingcheng Kong Dong Zhao Guodong Jiang Genjie Jiang Yucai Shen

Simultaneously improving the thermal conductivity and flame resistance of epoxy composite is still a challenge. Herein, a novel epoxy composite with high thermal conductivity and greatly enhanced flame retardancy was developed through constructing integrated three-dimensional (3D) network based on boron nitride (BN), talc, ammonium polyphosphate (APP). The thermal conductivity of the composite with filler network reached 3.04 Wm −1 K −1 , which was 15.2 and 3.1 times of those of pure epoxy and sample with random filler distribution. The LOI value of the composite with filler network reached 37.8%, which was 1.9 and 1.4 times of those of pure epoxy and sample with random filler distribution, respectively. In addition, the effects of various combinations of filler on the flame resistance of the epoxy composite were also evaluated. The prepared composite with filler network exhibited excellent shape stability and mechanical strength even after ablation at 1000°C. The network structure constructed by BN had a positive effect on heat transfer, while APP led to the formation of phosphoric acid at high temperature, adhering to talc and other residues together. A ceramic-like residue was formed on the firing surface, which enhanced the barrier effect of char layer and flame resistance of the composite.

Preparation and properties of ceramifying silicone rubber

Journal of Nanjing University of Technology (2011)

Tingwei Wang

Ceramifying silicone rubber was prepared by blending silicone rubber and low softening point glass frit on a two roll mill.The effects of the glass frit on the tensile properties,ceramifying temperature,thermal shock resistance and compactness were investigated.The elongation at break of silicone rubber/glass decreased from about 180% to 110% with glass increasing,while the tensile strength was a little change between 6-7 MPa,and ceramifying temperature decreased from 750 ℃ to 600 ℃ with glass increasing.Thermal shock resistance could be improved with glass increasing.The scanning electron microscopy analysis showed that there were many pores in the ceramic residue,thus resulting in a bad compactness.

A demand-based caching method for garbage collection in flash-memory embedded systems

2022 IEEE 11th Global Conference on Consumer Electronics (GCCE) (2017)

Chin-Hsien Wu Tingwei Wang

NAND flash memory has been used for the data storage of mobile devices, Laptops, and various embedded systems, but requires a garbage collection mechanism due to its erase-before-write characteristic. Garbage collection consists of a series of activities (such as read, write, and erase operations) that usually degrade the lifetime and the performance of NAND-based storage systems. In this paper, we propose a demand-based caching method for garbage collection in flash-memory embedded systems. The experimental results show that the proposed method can cache a small part of appropriate information about garbage collection in RAM-limited embedded systems and the performance is still reasonable.
