Abstract
Adding acid-modified resin compatibilizers is essential for plastic composites reinforced with carbon-neutral cellulosic filler. Researchers have measured the efficacy of adding a compatibilizer in the context of mechanics. However, it is necessary to microscopically clarify how the compatibilizer actually works for quality control and further expansion of applications. In this review, the author first describes the situation of cellulosic composites and presents issues regarding how one assesses the role of the compatibilizer. The author then reviews recent multi-scale experimental approaches to the detection of covalent bonds between the cellulosic filler and compatibilizer, estimation of nanoscale interphases, and the micron-scale dispersibility of the fillers. With accumulation of such experimental facts, appropriate parameter settings can be expected for the structural analysis such as the finite-element method, as well as the potential to provide appropriate explanatory variables for material/process informatics.

Summary
This article reviews investigations on elucidating the functions of acid-modified resin compatibilizers as experimentally as possible, from the mechanical properties of. If one faces unexpected problems with respect to the reproducibility of physical properties, such as formability and appearance, the main factors should be identified by microscopic and systematic criteria. By accumulating such mechanistic understanding, the reliability of composites will be improved and composites will be expanded to new markets. This article reviews investigations on elucidating the functions of acid-modified resin compatibilizers as experimentally as possible, from the mechanical properties of the final bulk composite materials and from molecular, nanometer, and micron scales. The experimental approaches exemplified here may be applied to other systems (e.g., glass fiber-reinforced plastics (GFRPs), carbon fiber-reinforced plastics, adhesion, lamination, and surface modification) that employ acid-modified resins
