We would like to introduce our study on "Morphological Observation of Cellulose Nanofiber (CNF) Composite Bioplastic Products." In the case of TEM observation of commercially available bioplastic tableware containing CNF, the dispersion state and internal structure (microfibrils) of CNF were clearly confirmed. Additionally, in the TEM observation of bioplastic straws, the straws in question contained cellulose fibers (microfibrillated cellulose) that were slightly wider than CNF within the PLA. [Observation Overview] ■ TEM observation of commercially available bioplastic tableware containing CNF ■ TEM observation of bioplastic straws *For more details, please refer to the related links or feel free to contact us.

Our website introduces "Morphological Observation of Cellulose Nanofiber (CNF) Composites." We have included photos of "TEM Observation Examples of HDPE/CNF" and "SEM Observation Examples of HDPE/CNF." In TEM observation, the dispersion state of fine CNF and the lamellar crystals of the surrounding resin can be observed, while SEM observation allows for the observation of the dispersion state of relatively larger CNF.

We would like to introduce our observation of cellulose nanofibers (CNF) using transmission electron microscopy (TEM). Utilizing the know-how we have developed in observing resin materials with TEM, we examined the CNF in the ink solids of commercially available cellulose nanofiber ballpoint pens. We observed CNF with a width of approximately 10 nm that appeared to be entangled with ink pigments, and it was found that the ink contains CNF with varying degrees of fibrillation. [Observation Results] - CNF with a width of approximately 10 nm that appeared to be entangled with ink pigments was observed. - Submicron-width CNF was also observed. - Several thin microfibrils, around a few nanometers in diameter, bundle together to form fibers approximately 100 nm thick. - The ink contains CNF with varying degrees of fibrillation. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the "Cellulose Nanofiber (CNF) Observation" conducted by our company. Utilizing the expertise we have developed in scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observation of resin materials, we observed commercially available cellulose nanofiber (CNF) samples. We were able to clearly view individual CNF microfibrils with thicknesses on the order of nanometers from the surface or cross-section. [Observation Details] ■ Scanning Electron Microscopy (SEM) Observation - More finely dispersed CNF ■ Transmission Electron Microscopy (TEM) Observation - Cross-sectional observation of finely dispersed CNF *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our observation of cellulose nanofibers (CNF) using transmission electron microscopy (TEM). Utilizing the know-how we have cultivated in observing resin materials with TEM, we conducted observations on commercially available cellulose nanofiber (CNF) samples. As a result, it was found that commercial CNF1 consists of several thin microfibrils bundled together, while commercial CNF2 consists of one or a few microfibrils bundled together. 【Structure】 ■ Commercial CNF1 - A CNF sample made up of several thin microfibrils, approximately a few nanometers in diameter, bundled together to form fibers about 100 nm wide. ■ Commercial CNF2 - A CNF sample consisting of a bundle of one microfibril or a few microfibrils. *For more details, please refer to the related links or feel free to contact us.

On our company website, we introduce "Observation of CNF composite materials using Transmission Electron Microscopy (TEM)." By utilizing the techniques developed through the observation of polymer crystal structures and the morphology of polymer alloys, including the production of ultra-thin sections with staining, we have made it possible to observe CNF (cellulose nanofiber) incorporated into resins. We also include photographs of the dispersion state of CNF in PE and enlarged images. Please take a look.

On our company website, we introduce examples of resin material observation using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). In the TEM observation examples, we include observations of CNF in PE, the higher-order structure of cell walls in PE foams, and the lamellar structure near the surface of HDPE. Additionally, in the SEM observation examples, we present comparisons before and after weather resistance tests of ABS resin, as well as cross-sectional structural analysis of automotive bumper materials. Please take a look.

We would like to introduce a molecular weight evaluation technology for cellulose materials. It enables the dissolution of difficult-to-dissolve cellulose in a short time and allows for the measurement of molecular weight distribution using GPC. Our unique pretreatment technology achieves the preparation of stable solutions suitable for rapid dissolution and GPC measurement. Additionally, we have accumulated know-how regarding resin separation technology, allowing us to isolate cellulose nanofibers (CNF) from composite materials and measure their molecular weight distribution. 【Measurement Example: Cellulose Molecular Weight Distribution】 ■ Our unique pretreatment technology enables the preparation of stable solutions suitable for rapid dissolution and GPC measurement. ■ The presence or absence of cellulose degradation before and after molding of composite materials, as well as during recycling, can be evaluated from changes in molecular weight distribution. *For more details, please download the PDF or feel free to contact us.

Our company conducts observations of the dispersed structures in plant-derived straw using a field emission scanning electron microscope (FE-SEM). We observe the dispersion of islands of plant fibers (cellulose) in a sea of natural plant-derived resin, with circular starch islands present at the interface. We examine the dispersion state of various plastic composite materials from low magnification (a few hundred times: relatively large aggregated structures) to high magnification (around 100,000 times: fine structures), depending on the purpose. [Features] ■ Observation of the dispersion state of various plastic composite materials from low to high magnification, according to the purpose. *For more details, please download the PDF or feel free to contact us.

We conduct dispersion structure analysis of block polypropylene using transmission electron microscopy (TEM). The EPR components inside the rubber domain and the lamellar crystals of PE can be clearly observed, as well as the lamellar crystals in the PP matrix. We can also observe composites that include not only block PP alone but also elastomers, other resins, and filler components such as cellulose nanofibers (CNF), so please feel free to contact us. ■ EPR components and lamellar crystals of PE inside the rubber domain can be confirmed ■ Lamellar crystals in the PP matrix can be clearly observed ■ Composites with added filler components can also be observed *For more details, please download the PDF or feel free to contact us.
