Global Wood Coatings Market Key Nanotechnology
Applications Wood has several weaknesses, such as
being delicate, non-flexible, and non- durable
due to termite attacks and other factors.
Applying surface coatings is one of the best ways
to reduce weathering degradation. However,
depending on the severity of exposure and the
type and properties of the coatings, refinishing
is needed every few years. According to Inkwood
Research, the global wood coatings market is
expected to project a CAGR of 4.45 during the
forecast period, 2024-2032.

• One approach to enhance the functionality and
  end-user value of nanocoatings is the addition of
  nanoparticles. These nanoparticles have very
  large surface- to-volume ratios due to their
  morphology, allowing them to interact intensively
  with their surroundings, given their nano size.
  Nanotechnology has been utilized in many sciences
  and can be used to improve the quality of many
  materials, including wood and wood composites.
  Nanotechnology in wood- based products thus
  warrants attention from all industry
  stakeholders.

• Nanocoatings enhance the durability of wood and
  non-wood products by utilizing nanoparticles and
  nano-delivery systems to make changes at the
  molecular level. One primary goal of these
  coatings is to inhibit the growth of
  microorganisms such as fungi and bacteria.
  Nanosized particles of metal oxides, including
  zinc oxide (ZnO), titanium oxide (TiO2), and
  cerium oxide (CeO2), have demonstrated strong
  antimicrobial properties.
• Research has focused on the direct deposition of
  nanoparticles onto wood surfaces or the
  functionalization of wood surfaces with
  nanoparticles. For instance, ZnO nanoparticles
  were successfully fabricated on bamboo timber
  surfaces using a simple low-temperature wet
  chemical method based on sol- gel-prepared ZnO
  seed layers. The findings showed that the treated
  bamboo timber had improved resistance against
  Aspergillus niger and Penicillium citrinum,
  though it had poor resistance against Trichoderma
  viride.
• Graphene also exhibits superior antibacterial
  properties. Consequently, a combination of
  reduced graphene oxide and nano-ZnO has been used
  to coat bamboo-based outdoor materials through a
  two-step dip-dry and hydrothermal process,
  significantly enhancing mold resistance and
  antibacterial activity.
• Similarly, nanostructured ZnO created through a
  hydrothermal process has effectively protected
  wood surfaces from biodeterioration.
• Nanoadditives for Water Absorption Improvement
• Wood is well known to be susceptible to water or
  moisture due to the hydrophilic nature of its
  cell wall polymer and its capillary-porous
  structure. The interaction between wood and water
  leads to biodegradation, dimensional instability,
  and accelerated weathering. Although conventional
  chemical modifications are used to enhance the
  hydrophobicity of wood, they do not completely
  prevent water accessibility. Additionally, the
  chemicals used in these treatments can be
  hazardous. As an alternative, nanotechnology is
  employed for wood modification and
  functionalization. Incorporating nanoparticles
  into polymeric coatings helps reduce water
  absorption on wood surfaces. Two main approaches
  are used to integrate nanoparticles into
  coatings solution blending and in situ addition.
• In the solution blending approach, a solvent is
  combined with the polymer before being applied to
  wood surfaces through methods like dipping,
  brushing, or spraying. The second approach, in
  situ addition, involves a chemical process where
  compounds are added directly to monomers,
  followed by polymerization. Nanoparticles are
  synthesized in situ on the wood surface through
  chemical reactions such as hydrothermal methods
  or sol-gel deposition.

• Nanoadditives for Mechanical Properties
  Improvement
• Inorganic particles integrated into organic
  polymers are commonly used in wood coatings to
  enhance mechanical properties. As fillers, the
  rigidity and hardness of the inorganic materials
  combine effectively with the polymers
  processability. However, when applied in micron
  size, inorganic particles have disadvantages,
  such as reducing the flexibility of the material
  and decreasing the transparency of the coating
  system.
• The utilization of inorganic particles in
  nanosize increases the surface area and the ratio
  of the interfacial area, which subsequently
  influences the properties of the raw material.
  Recent studies have investigated using
  nanocellulose as a renewable reinforcement to
  develop a bio-based nanocomposite coating system
  with improved performance.
• Nanosilica is another common nanoparticle applied
  to improve mechanical properties. Among the
  advantages of using nano-silica are its high
  hardness and the ability to be easily chemically
  modified to enhance its compatibility with the
  polymer matrix. (Source)
• Future of Nanotechnology in the Wood Coatings
  Market
• The building and construction industry is
  increasingly incorporating nano- technology-based
  coatings to enhance the performance, durability,
  and aesthetic appeal of structures. These
  coatings offer several advantages, notably in
  providing enhanced protection against
  environmental factors like UV rays, water, and
  air pollution. For instance, applying
  nanocoatings to building façades can mitigate the
  accumulation of dirt and grime, preventing
  discoloration and premature aging while
  safeguarding the structure against moisture and
  other environmental stressors. (Source)
• Moreover, certain nanocoatings can mitigate heat
  transfer, effectively cooling buildings during
  hot weather and lessening reliance on air
  conditioning.
• Additionally, they can regulate light absorption
  and reflection, thereby
• enhancing energy efficiency by reducing the need
  for artificial lighting.
• The adoption of nanotechnology-based coatings
  also presents notable sustainability benefits in
  the global wood coatings market. Many of these
  coatings utilize eco-friendly materials and boast
  prolonged durability, minimizing the frequency of
  maintenance and replacement. This not only
  curtails waste but also diminishes the
  environmental footprint associated with building
  and construction endeavors.
