Influence of pineapple leaf particulate on mechanical, thermal and biodegradation characteristics of pineapple leaf fiber reinforced polymer composite

Journal of Polymer Research, 2021
Natural fibers are gaining too much attention and researchers are shifting their interest due to environmental concern and ecological benefits. The present experimental study is focused on the investigation of thermo-mechanical properties of aggro–waste pineapple leaf fiber (PALF) reinforced polymer composite under the influence of pineapple micro ...

Isolation of nanocellulose from pineapple leaf fibres by steam explosion [PDF]

Carbohydrate Polymers, 2010
Steam explosion process is employed for the successful extraction of cellulose nanofibrils from pineapple leaf fibres for the first time. Steam coupled acid treatment on the pineapple leaf fibres is found to be effective in the depolymerization and ...

Chemical modification of pineapple leaf fiber: Graft copolymerization of acrylonitrile onto defatted pineapple leaf fibers

Journal of Applied Polymer Science, 2000
Graft copolymerization of acrylonitrile (AN) onto defatted pineapple leaf fiber (PALF) was studied using a CuSO4 and KIO4 combination as an initiator in an aqueous medium in the temperature range 30–500C. The effects of the concentration of potassium periodate, CuSO4, and monomer on the graft yield were investigated.

Preparation of Pineapple Leaf Cellulose Membrane

Advanced Materials Research, 2014
In this study, the pineapple leaf cellulose membrane was prepared after being dissolved in ionic liquid (1-butyl-3-methylimidazolium chloride ([Bmim]Cl)) and high pressure microfluidization process. The chemical morphology and structure of cellulose membrane were measured by scanning electron microscope (SEM), fourier transformed infrared spectra (FT ...

Pineapple Leaf Fibre: Cultivation and Production

2020
A pineapple leaf fibre (PALF) is classified according to the sources in plants, where they occur and from which they are extracted. PALF is considered to be superior in texture than any other vegetable fibre. It helps in climate restoration and soil quality by preventing soil erosion. This chapter includes pineapple cultivation practices, plant anatomy,

Pineapple Leaf Fibres for Automotive Applications

2020
Fibre-reinforced polymer composites (FRPCs) are playing a significant role in manufacturing of goods/products in service for lightweight applications. Among FRPCs, natural fibre-reinforced polymer composites (NFRPCs) are one in forefront and replacing both the conventional and unconventional reinforced composites since they are eco friendly in nature ...

Anatomical Structure of Pineapple Leaf Fiber

2020
The use of natural fibers, such as pineapple, sisal, banana, coir, sun hemp, mesta, or jute, in polymer composite materials has expanded fundamentally in recent years. Today, pineapple fiber is enormously popular among the composite research community due to its various advantages including its smoothed and scaled morphology, low thickness, firmness ...

Purification and Characterization of a Pineapple Crown Leaf Thiol Protease

Preparative Biochemistry and Biotechnology, 2004
A thiol protease was isolated and purified from the crown leaf of pineapple, Ananas comosus (L.) Merr. cv. Queen, by an immunoaffinity procedure. After the purification to electrophoretic homogeneity, the enzyme was characterized with respect to some of its physico-chemical and kinetic properties.
