Injection molding permits manufacturing of complex three-dimensional polymer products with nanostructured surfaces in less than 30 seconds. New work has explored the practical limits of feature size during injection molding. Surfaces with a range of nano and submicron-scale structures were molded from amorphous and semicrystalline thermoplastic polymers having a range of molecular weights, flow promoters and related additives, and loadings of nanoparticulate fillers. Replication of the surface features was correlated with the polymer chain length (molecular weight), additive mobility, and filler loading.
