Effect of a nanocellulose on the optical and mechanical properties of flax pulp

Popis výsledku v původním jazyce

In the interest of our times, novel or modified materials are studied to create and enhance today's materials. Flax pulp is used because of its higher mechanical properties. This paper modified this material with the addition of nanocellulose to determine/assess the possibility of increasing some of the properties. Mechanical examinations assessed differences in properties, such as tensile strength, breaking length, and tensile energy absorption. For further determination, an optical examination was performed to evaluate colour differences in individual materials produced in this work. Different types of applications were compared to paper without the addition of nanocellulose. Specifically, nanocellulose was added to pulp mass and applied to a paper by spraying, coating, and lastly by using ultrasound. Results for mechanical properties are best for application form of spraying in terms of least use nanocellulose (3.5%) and the highest mechanical properties in most cases compared to reference paper product. The colour difference is the highest for those applications, where nanocellulose addition was more sufficient for two-layer coating, spraying, and using ultrasound. Data from this work serve as an extension to nanocellulose utilization for paper products, whether it may enhance specific properties of modified material.
