Special Issue Information

Dear Colleagues,

Wood polymer composites (WPC) have grown rapidly because of their low cost, durability, and sustainability. WPCs are a type of composite material that combines raw wood material with various polymers to prepare a high-performance composite product with improved mechanical properties. They are commonly used in outdoor decking, fencing, furniture, and building materials. In addition, novel WPCs, including wood aerogels and hydrogels, wood-based sensros, and wood radiative cooling materials, have received increasing attention due to their broad prospects in the field of new materials and energy. Novel WPCs are generally made from cellulose combined with various functional polymers via “bottom-up” or “top-down” methods.

This Special Issue on “Wood Polymer Composites: Properties, Processing and Applications” will curate recent advances in the design, synthesis, characterization, and utilization of wood polymer composites, highlighting some of the challenges in the development and implementation of these materials. Topics will include but are not limited to:

  • Traditional wood polymer composites, including plywood, particleboard, fibreboard, and wood plastic composites;
  • Novel wood polymer composites, such as wood aerogels and hydrogels;
  • Polymer composites prepared from the main compoents of wood, including cellulose, hemicellulose, and lignin;
  • Wood adhesives and various polymers used for preparing wood polymer composites.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Under a global carbon-neutralizing environment, renewable wood is a viable alternative to non-renewable resources due to its abundance and high specific strength. However, fast-growing wood is hard to be applied extensively due to low mechanical strength and poor dimensional stability and durability. In this study, epoxy-acrylic resin-modified wood was prepared by forming a functional monomer system with three monomers [glycidyl methacrylate (GMA), maleic anhydride (MAN), and polyethylene glycol-200-dimethylacrylic acid (PEGDMA)] and filling into the wood cell cavity. The results showed that in the case of an optimal monomer system of nGMA:nPEGDMA = 20:1 and an optimal MAN dosage of 6%, the conversion rate of monomers reached 98.01%, the cell cavity was evenly filled by the polymer, with the cell wall chemically bonded. Thus, a bonding strength of as high as 1.13 MPa, a bending strength of 112.6 MPa and an impact toughness of 74.85 KJ/m2 were applied to the modified wood, which presented excellent dimensional stability (720 h water absorption: 26%, and volume expansion ratio: 5.04%) and rot resistance (loss rates from white rot and brown rot: 3.05% and 0.67%). Additionally, polymer-modified wood also exhibited excellent wear resistance and heat stability. This study reports a novel approach for building new environmentally friendly wood with high strength and toughness and good structural stability and durability. Full article
