The double cantilever beam test (DCB) was used to estimate the fracture toughness of poly(methyl-methacrylate) (PMMA). With the help of given neutron reflectometry (NR) results for PMMA a correlation between fracture toughness and interface width was established. It displays a three regime behaviour similar to polystyrene (PS). For the first time, deformation and defect structures in the vicinity of the crack tip were investigated by scanning ultra-small angle X-ray scattering (S-USAX) where a beam from a synchrotron source is scanned over the sample. It is concluded that crack propagation during the DCB measurement is connected with large deformations and defect formation, where the plastic deformation zone extends over a large size (>400 μm). Following a model for scattering from diffuse boundaries it was concluded that the diffusiveness increases from the outer edges to the centre of the plastic zone. S-USAX thus provides details of sample failure at a microscopic level as well as information about the structure of the defect boundaries and their distribution across the plastic zone.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
