Can WPC animal sculptures be engineered to self-heal minor scratches or surface damage?

WPC (Wood-Plastic Composite) animal sculptures are popular for their durability and aesthetic appeal, especially in outdoor settings. But can they be engineered to self-heal minor scratches or surface damage? Advances in material science suggest it's possible. By incorporating self-healing polymers or microcapsules filled with repair agents, WPC sculptures could autonomously repair small cracks or scratches when exposed to heat, sunlight, or moisture. This innovation would significantly extend their lifespan and reduce maintenance. While current WPC materials aren’t typically designed for self-repair, ongoing research into smart composites hints at a future where self-healing outdoor sculptures become a reality. For now, protective coatings remain the best solution to preserve their appearance.
