AFM combined with infrared (IR) spectroscopy, known as AFM-IR, is a novel technique to acquire the information of the nanoscale spectrum. Wide range of cross related research activities in photovoltaics, photo electrocatalysis novel LED materials, can be categorized in energy research fields.58–61 AFM-IR with its advantages in revealing nanoscale chemical information can help to investigate nanoscale heterogeneity and degradation in organic hybrid perovskite material. Frontier research topics such as ferro-elasticity in perovskite and site varying activity in novel catalytic materials can now be studied with high resolution.62,63 Future applications might include nanoscale chemical identification of interfacial defects and corresponding inhibition in materials or device.

Recently, combination with other techniques, such as optical spectrum, empowers AFM a more incredible technology to acquire more interfacial information, especially for surface chemical composition and distributions. This technology strongly promotes our understanding of the interface at the micro-nano scale. For example, to regulate the modification of polymer membrane, atomic force microscopy infrared (AFM-IR) was utilized to observe the chemical composition and distributions of polyethersulfone and polyvinylpyrrolidone as shown in Figure 7 (Morsch et al., 2017). The IR mapping shows extremely high resolutions. To date, other combination of AFM with spectrum technique has made a breakthrough, such as AFM-fluorescence, AFM surface-enhanced Raman scattering (SERS) (Frederickx et al., 2018; Fu & Zhang, 2017; Harvey et al., 2012). It can be foreseen that these novel AFM characterization methods will create research opportunities in the field of environment.
