“…It appears that in the bottom layer of the film some more stable -presumably more crosslinked -domains are formed and those domains resist the wash-off. Those features can be actually the initial stages of the film growth as reported for PAVTD of polyethylene [43].…”

Carboxyl-enriched nanoparticles are produced by the plasma polymerization of acrylic acid (ppAA NPs), whereas plasma-assisted vapor-phase deposition is used to prepare thin films of poly(ethylene oxide) (ppPEO). Sequential depositions generate phase-separated coatings. The ppAA NPs are found to be in a glassy state, whereas thin films of ppPEO are found to be in a rubbery state. When immersed into a solution of lysozymes, the ppPEO absorbs water, which results in the dissociation of the carboxyls on the ppAA NP surface. Negatively charged carboxyls attract positively charged lysozymes. The ppPEO surface in between the NPs resists the accumulation of the protein, leading to the spatially localized adsorption of lysozymes only on the spots where the ppAA NPs are located.

“…In the equilibrium state, crystal growth primarily proceeds from smaller building blocks to form larger structures (such as spherulites, lamellae, pyramidal spiral crystals, and so forth). Zhai et al systematically investigated the crystalline morphology and [89] Copyright 2019, Elsevier Ltd formation mechanism of PEO on silicon wafers. [90] In Figure 6, the crystals are raised slightly higher than the inner edge, and this height difference will cause the raised inner crystals to disappear and some holes to appear (see Figure 6B), causing the crystals to become more irregular as the melting temperature changes (see Figure 6C,D).…”

With the rapid development of polymer materials, the simultaneous acquisition of micro‐nano structure and mesoscopic mechanical properties from the material surface with the transverse resolution of nanoscale has become a hot spot in the research of polymer materials. Atomic force microscopy‐based high‐resolution imaging and single‐molecule force spectroscopy techniques have been widely used in various related fields. This review introduces the basic design and working principles of atomic force microscopy as well as single‐molecule force microscopy and their applications in the characterization of polymer surface morphologies, polymer film phase separation, polymer crystallization behavior, polymer chain stretching, protein folding/unfolding, G quadruplex intermolecular and intramolecular interactions, living cell surface proteins, and sugars. The research status of AFM probe modification strategies such as nanomaterial processing, single molecule manipulation and biomolecule etching is reviewed, finally, the limitations and improvement potential of single molecule force spectroscopy based on atomic force microscopy (AFM‐ SMFS) are summarized and discussed, and the new research practice in the field of polymer materials is prospected.
