Plastic wood composite materials and their products themselves have excellent performance. With the deepening of research and market expansion, it is necessary to adopt new concepts and methods in material promotion, product development, user experience, and other aspects to guide their high value-added utilization. The functionalization of plastic and wood products can guide the material research and development process, directly linking user needs with material research and development, making user experience more important. Clarifying the path of functional development of plastic and wood products, enriching the design space of products, providing methods to optimize product experience, and promoting the high value-added utilization and healthy and sustainable development of plastic and wood products.

The ways to develop functionalized plastic wood products include improving the formula system, improving the molding process, and designing secondary processing. By adjusting the formula system, such as using different components, proportions, and mixing sequences to achieve differences in material performance; By controlling the molding process, the material has different structures and physical and chemical properties after molding; Through secondary processing design, products can have new structural shapes or functions, such as enhancing their sound absorption and noise reduction effects by drilling honeycomb shaped micropores on the surface of plastic wood interior wall panels. Plastic wood is flammable, and the smoke generated by combustion can cause harm; During long-term use, the physical and mechanical properties of materials will decrease; In addition, the presence of biomass components in plastic wood materials can also cause them to be damaged by microorganisms, which are important influencing factors that promote the functional research and development of materials.

With the continuous increase of urban population, urban construction is increasingly attracting people's attention. At present, the advanced concept of urban construction is green construction, which combines urban construction with nature. Therefore, if plastic wood composite materials are used to decorate the green plants of the city, this will be clearly reflected, because the initial urban greening is decorated with materials such as limestone and ceramic tiles, which will appear very industrialized. Considering the color of plastic wood composite materials, different plants have different colors, so different colored materials are needed for decoration. For example, darker green flowers and plants can be decorated with light colored plastic wood composite materials; Lighter colored lilies and other flowers can be decorated with darker colored plastic wood composite materials. From the perspective of the combination method of composite materials, different material connection methods achieve completely different effects. For example, connecting with circular horizontal composite materials with a certain gap in the middle can allow plants to fully absorb oxygen; On the other hand, from the appearance, the entire flower bed has become an exceptionally beautiful scenery in the city. In addition to flower beds, trash cans are also a major hidden danger in urban greening. If a sudden trash can is placed in the center of the city, it can greatly damage the beauty. The use of plastic wood composite materials can precisely solve this problem. The garbage bins made of wood materials not only cater to the main body of urban greening, but also ensure the durability of the garbage bins due to the corrosion resistance of the plastic wood composite materials.
