Spatially resolved indiffusion behavior of Cu 2+ and Ni 2+ in polypropylene

Microplastics and their effects on the environment and food chain have become increasingly important in recent years. These polymer particles, which are only few millimeters in size or smaller, accumulate in the environment and can enter the human food chain via animals that ingest them. Moreover, t...

Description
Summary:Microplastics and their effects on the environment and food chain have become increasingly important in recent years. These polymer particles, which are only few millimeters in size or smaller, accumulate in the environment and can enter the human food chain via animals that ingest them. Moreover, they can accumulate impurities such as heavy metals. Therefore, this study focuses on the indiffusion behavior of metal ions into semicrystalline polypropylene (PP) applying time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) at cryo‐conditions. Diffusion coefficients of Cu 2+ and Ni 2+ in PP are determined by classical SIMS depth profiling in frozen state ( T
