Fabrication of porous tubular carbon fibers from the fruits of Platanus orientalis and their high oil adsorption properties

A novel natural fiber from plane tree (Platanus orientalis L.) fruits to reinforce polypropylene composites

“…The fibers are naturally hollow inside and are separated from each other by a wall at the expanding node sections. 8 The average external fiber diameter was 33.1 ± 6.9 μm for internode regions and 43.9 ± 3.3 μm for node regions. The tube wall thickness was found as 4.6 ± 0.6 μm, consistent with the literature.…”

“…As known from the literature, lignin decomposes slowly over a wider temperature range, while cellulose and hemicellulose decompose faster between 200°C and 500°C. 6,8 The mass loss, indicated by stage II between 270°C and 343°C, is thought to be due to the total decomposition of cellulose, hemicellulose and some part of lignin. The main wood components volatilize at this stage and a large amount of mass is lost (55.09%).…”

“…Moreover, the lignin-crosslinked monosaccharide layer surrounding the fiber surface causes corrugated ripples. 8 It is known that increasing the surface roughness topography of the fibers produces a similar mechanical interlocking effect and enhances the friction between the constituents. 3 The ultimate tensile strength of bamboo is relatively higher than most other fiber plants.…”

“…6 It has also been reported that the raw fibers are hydrophobic and do not sink in water. 8,10 Apart from the above mentioned works, no study has been found in which PTFs are combined with a polymer matrix and their structural and mechanical properties are examined.…”

“…The fibers also assist in protecting the seeds from natural events such as rain. 8 While plane trees can be grown in many parts of the world and used for different purposes (furniture, flooring, medicine, printing, street and garden greening, etc. ), the abundant quantities of plane tree fruits have remained behind as bio-waste material.…”
