How can wood-plastic composite (WPC) be treated to emit a wood-like aroma in sculptures?

Wood-plastic composite (WPC) sculptures can be engineered to emit authentic wood-like aromas through several technical approaches. Essential oil infusion during manufacturing involves blending concentrated wood essences like cedarwood or sandalwood oils with the composite material before extrusion. The porous structure of WPC allows for effective scent absorption when treated with alcohol-based fragrance carriers that penetrate the material matrix. Microencapsulation technology offers advanced solutions by embedding scent capsules within the composite that release aroma through gradual breakdown or pressure activation. Surface coating with scented polymer varnishes containing volatile organic compounds (VOCs) from real wood provides immediate olfactory appeal while protecting the artwork. For lasting effect, internal fragrance reservoirs can be incorporated into hollow sculptures using scent-diffusing mechanisms that maintain aroma consistency through controlled release systems. These treatments not only enhance artistic value but also create multisensory experiences without compromising the material's structural integrity or durability.
