Special Issue Information

Dear Colleagues,

Biomass-based materials have attracted increasing interest in recent decades because of their advantages in cost, renewability and environmental protection. Using biomass-based materials to replace the traditional fossil-based materials in our daily life is of great significance in reducing carbon emissions. Therefore, novel strategies for preparing materials using biomass (cellulose, hemicellulose, lignin, chitosan, polyphenols, collagen, etc.) in various application fields are crucial.
This Special Issue titled “Biomass-Based Material” will focus on the preparation, characterization, properties and application of novel materials from lignocellulosic biomass, chitosan, starch, polyphenols etc. Scientists are kindly invited to contribute communications, original research articles and review articles.

Abstract
Plywood is made of wood veneers that are bonded with adhesives such as urea-formaldehyde, phenol-formaldehyde and melamine-formaldehyde resins. The plywood made from formaldehyde-based adhesives not only releases formaldehyde but also relies on fossil resources.

Plywood is made of wood veneers that are bonded with adhesives such as urea-formaldehyde, phenol-formaldehyde and melamine-formaldehyde resins. The plywood made from formaldehyde-based adhesives not only releases formaldehyde but also relies on fossil resources. In this article, we synthesized furan-acetone adducts from lignocellulosic biomass in one pot. The furan-acetone adducts could be directly used as adhesives with the addition of phosphoric acid as a curing catalyst. Particularly, with the addition of 5 wt% diphenylmethane diisocyanate (MDI) as a crosslinking agent, both the wet and dry bonding strength of the plywood prepared from the adhesives could meet the minimum requirement of 0.7 MPa (Chinese National Standard GB/T 9846-2015). The possible adhesion mechanism is that the penetration of furan-acetone adhesives into vessels and cell lumens followed by crosslinking during hot-pressing forms mechanical interlocking at the interface of wood veneers, which provides the main bonding strength of plywood. The findings presented here could provide a new way for the efficient preparation of aldehyde-free green wood adhesives and the value-added utilization of woody biomass. Full article
