Special Issue Information

Dear Colleagues,

Biomass materials are high-molecular-weight materials produced by nature, which produces a sustainable development of resources. Biomass resources are mostly produced by plants or animals, such as various natural cellulose, chitin, lignin, polysaccharides, starch, rubber, natural resins, leather, nucleic acids, proteins, etc. The quantity of biomass resources synthesized by plants growing on the Earth every year is as high as 100 billion tons, and the biomass resources produced by animals have an even higher quantity. A variety of functional materials can be synthesized by using biomass resources, such as plant or animal tissue waste through different strategies and approaches. Although the research on biomass materials has been quite extensive, their research and application in food, environmental protection, energy, medicine, biology, and other fields are still worth discussing and paying attention to.

This Special Issue, “Biomass Materials in Materials Chemistry: Preparation and Characterization, 2nd Edition”, welcomes original research and review articles in the field, focusing on the relationship between the synthesis, preparation, and application of biomass-based materials. From agriculture to medicine, and from pharmacology to chemistry, the contributions on these biomass resources in different applications such as catalytic carriers, pharmaceutical carriers, food packaging, thickening agents, etc. are also welcome.

Gypsum-based composites were prepared via a slurry casting process using construction gypsum as the binding material and poplar fibers as reinforcing material. The effects of different fiber content and curing time on the mechanical properties, water resistance, and flame retardancy of these composites were investigated, and the influence mechanism was characterized by infrared spectroscopy, scanning electron microscopy, and X-ray diffractometry. The results showed that the best composite mechanical strength was achieved with 10% poplar fiber- content, and the absolute dry flexural and compressive strengths reached 3.59 and 8.06 MPa, respectively. Compared with pure gypsum, the flexural strength and compressive strength increased by 10% and 19%, respectively. The inclusion of fibers somewhat prevented the migration of free water within the composites and enhanced their water resistance. At 10% fiber content, the composite’s 24 h water absorption rate was 34.3%, 8% lower than that of pure gypsum, with a softening coefficient of 0.55. However, fiber content increases the porosity of gypsum-based composites. When heated, this increased porosity accelerates’ heat conduction within the matrix, raising the peak and total exothermic rates, thereby weakening the composites’ inherently flame-retardant properties. Poplar-fiber-reinforced gypsum-based composites offered superior performance in commercial applications, compared to pure gypsum board, providing a sustainable and green alternative for ceilings, partitions, and other applications, while broadening the prospects for gypsum-based composites in the engineering field.
