Special Issue Information

Dear Colleagues,

Bio-based materials such as wood, bamboo, and their composites have attracted attention among researchers due to their eco-friendly nature. Moreover, their products have been used in daily life, such as in furniture, construction, and even aerospace. However, owing to the drawbacks of natural polymers in cell walls, their applications undergo various challenges. Surface modification and protection can overcome defects and even endow bio-based materials with multi-functions, such as dimensional stability, hydrophobicity, anti-fungal properties, and flame retardance. Many kinds of modification techniques have been reported to achieve the target for which an improvement in overall performance is expected. Driven by the current state of ideas and techniques for modification, it is necessary to understand the mechanisms of the modification and protection processes. Further, we welcome papers that explore potential ideas for modification and protection.

This Special Issue will serve as a forum for papers focusing on the following concepts:

  • Eco-friendly methods for the modification and protection of bio-based materials;
  • Modification and protection with multi-functions;
  • Experiments with new methods or characterizations on surface modification and protection;
  • The development of mechanisms for the modification and protection of bio-based materials;
  • Advanced material preparation and characterization made from bio-based materials.

We look forward to receiving your contributions!

Paper has the multiple advantages of being breathable, sustainable, environmentally friendly, and non-toxic for medical care. However, the flammability stemming from the raw materials of paper has limited its use in medical heat therapy. In this paper, a composite flame-retardant coating is assembled layer by layer on a medical paper surface using medically safe natural biomaterials with starch and adenosine triphosphate as internal layers, and starch and phytic acid as external layers. With the layer-by-layer assembly using the ultrathin adsorption method, the microscopic morphology and elemental mapping reveal that all the biomaterials are deposited uniformly and have completely capsulated the paper surface fiber. The flame-retardant coating shows less impact on medical paper appearance morphology and mechanical properties in medical usability. The coated medical paper exhibits significant flame-retardant performance, such that the limiting oxygen index increases from 19.70% to 25.40% where both internal and external layers reached 100 layers (BL), and relevant residual charring in the thermogravimetric test increases 17.00 wt% in a nitrogen atmosphere and 18.00 wt% in an air atmosphere at 800 °C. The peak and total heat release rates of 100 BL medical paper reduced by approximately 91.10% and 53.10%, respectively, and the variations in both CO and CO2 production also suggest that flame-retardant coating could effectively inhibit combustion. Benefiting from the intumescent flame-retardant function of different biomaterial combinations and the multilayer design on different thermal response temperatures, the flame retardancy of medical paper significantly improved, and this advancement will make medical heat therapy safer and healthier for patients.

Most traditional adhesives applied in the wood industry are synthetic resins obtained from petroleum. However, the production of these resins raises substantial environmental issues because of formaldehyde release, which leads to detrimental impacts on both human health and the environment. In contrast, bio-based adhesives offer an eco-friendly option that is created by renewable biomass resources. These adhesives can effectively overcome the above problems. Hence, it is crucial to pay more attention to bio-based adhesives. However, the inherent characteristics of the raw materials used in the production of bio-based adhesives result in a number of limitations, including weak bond strength, poor water resistance, and susceptibility to mildew, which restrict their further applications. Most researchers have used physical and chemical methods to modify bio-based adhesives in order to improve their overall performance. The defects of bio-based adhesives, including their limited bond strength, inadequate resistance to water, and vulnerability to mildew, are summarized in this paper, and the investigation of potential modification methods on bio-based adhesives is reviewed. Moreover, we encourage the widespread use of bio-based adhesives in various fields to promote sustainable development due to their eco-friendly characters. Full article
