Wood and Polymers

Natural materials and materials from plant or animal origin such as wood, cotton, paper products, wool, and leather are fully biodegradable under aerobic conditions. Combined chemical, physical, and biological attack may cause polymers to be biodegradable by a combination of chemical, physical, and biological attack (51, 55).

Sanadi et al. [2] indicate that there is no evidence of chemical reaction at the interface between wood and polymer the interfacial adhesion between both materials appears to be solely through mechanical interlocking. However, according to W linder and Gardner [19], there are five main adhesion mechanisms recognized in fhe interface between wood particles and plastic (i) adsorption (also referred to as wetting), (ii) mechanical interlocking,... 

Inverse gas chromatography (IGC) is a method very well used by the adhesion community for obtaining thermodynamic and morphological information on a variety of materials such as fillers, pigments, colloids, fibers, powder, wood, and polymers [17,60,61,85-94]. The term inverse means that the stationary phase is of interest by contrast to conventional gas chromatography in which the mobile phase is of interest. Its success lies in the fact that it is simple, versatile, usable over a very wide range of temperature, and very low cost. IGC has a well established background for the assessment of yg acid-base parameters for polymers and fillers. Such thermodynamic parameters can be further used to estimate the reversible work of adhesion at polymer-fiber and polymer-filler interfaces [95,96],...

Azole fungicides represent a new class of microbicides with favourable toxicological property patterns and low ecotoxicity some of them are suitable for the fungicidal treatment of various materials, especially wood and polymers. 

The properties of polymer-wood materials based on virgin and recycled low density polyethylene (LDPE), PS, and their blends (LDPE-PS) were studied [21] and it was found that reactive groups in recycled polymers bring about chemical and specific interactions at the polymer-wood and polymer-polymer interface, thus improving the mechanical properties of these materials.

It has been found that IR imaging enables visualizing the distribution of not only wood compounds but also wood particles in the polymer matrix within wood-plastic composites (Figure 6.17) [107]. The interaction at the interphase between wood and polymers, glue, or paint is often critical for product performance and can be investigated accurately using IR spectroscopy [99].
