The following methods can be used to determine the fiber morphology of plant fiber raw materials:
Optical Microscopy: A microscope is used to observe the shape and size of plant fibers. This method can be used to measure the length, diameter, wall thickness and other parameters of the fiber, and can observe the morphological characteristics of the fiber, such as shape, branching situation, surface structure and so on.
Scanning electron microscope (SEM): The surface morphology and structure of plant fibers can be observed using SEM, including surface texture, pores, etc. This method also allows for higher magnification and greater detail.
Transmission Electron Microscopy (TEM): The internal structure and details of plant fibers can be observed using TEM, including the thickness and shape of the fiber wall, fiber hollow and pores, etc.
Cellulose Morphology Analyzer: This is an instrument specially used to analyze the shape of plant fibers. It can measure the length, width, diameter, angle and other parameters of fibers, and can analyze the morphological characteristics and distribution of fibers.
The above methods can be used alone or in combination to obtain more comprehensive and accurate fiber morphology information of plant fiber raw materials.
