A Review: Efficiency Of Nanocrystals And Nanofibrils Cellulose As Reinforcing Element In Composite Films Productions

Cellulose nanocrystals and nanofibrils are nano-sized cellulose obtained by top-down approaches such as isolation and extraction both by chemical and physical methods. Due to the abundance, high-strength, and high-stiff properties of nanocrystals and nanofibrils, they can be used as reinforcement for composite films. This review aims to demonstrate the efficiency of cellulose nanocrystals and nanofibrils as reinforcement for composite films based on the mechanical properties, surface wetting, and crystallinity of the resulting composite films. The method used is to find articles related to the use of nanocrystals and nanofibrils as reinforcing elements on online journal website pages, there are 10 articles used that are related in this review. The result of this literature review is that the use of nanocrystals and nanofibrils for composite film reinforcement can be said to be effective. Based on the composite films formed, almost all types of composite films have high mechanical properties, better surface wetting, and higher crystallinity than without the addition of nanocrystals and nanofibrils as reinforcement composite film. Therefore, this paper can provide information on the effectiveness of nanocrystals and nanofibrils as reinforcement in composite films so that these composite films can be further utilized to make good materials
