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

Abstract: 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. The effects of time, temperature, amount of some inorganic salts, and organic solvents on the graft yield are also reported. A combination of Cu+2—IO −4 in an aqueous medium with an IO −4 concentr… Show more

“…Ananas (Ananas comosus), Bromeliaceae ailesine ait çok yıllık otsu bir bitki türüdür [6,17,18,20,23,26,27,29,32,34,37,[41][42][43]. Eni ve boyu 1-2 m arasında değişiklik gösteren bu bitki meyve etrafında çevrelenen yaklaşık 2,5-6 cm kalınlığında ve 90-140 cm uzunluğunda yapraklardan (20-30 adet) oluşmaktadır [26-28, 32, 41].…”

“…Eni ve boyu 1-2 m arasında değişiklik gösteren bu bitki meyve etrafında çevrelenen yaklaşık 2,5-6 cm kalınlığında ve 90-140 cm uzunluğunda yapraklardan (20-30 adet) oluşmaktadır [26-28, 32, 41]. Genellikle kıyı kesimlerde ve tropikal iklime sahip bölgelerde yetiştirilen ananas bitkisinin dünyadaki yıllık üretimi FAO (Food and Agriculture Organization)'nun 2011 değerlerine göre 21,9 milyon ton civarında olduğu kaydedilmiştir [29,32]. Bu bitkinin yetiştirilme amacı her ne kadar çoğunlukla meyvesi olsa da, 1 hektar alandan tonlarca taze ananas bitkisi yaprağı elde edilebilmektedir [11,34].…”

“…presents wide genetic diversity, mainly in Brazil, one of the centers of origin and dispersion of these Bromeliaceae (SOUZA et al, 2007;2012). This genetic variability, however, has been little explored yet, in spite of the potential of these plants to generate several products, mainly fibers for the manufacture of rustic material, such as ropes and fabric; the use in the automotive industry as a source of nanocellulose plastic, more resistant ho heat, gasoline and water and he envisions using it for dashboards, bumpers and body panels (LEÃO et al, 2009;MOHANTY et al, 2000;ZAH et al, 2007), manufacture of paper (MARQUES; GUTIÉRREZ; DEL RIO, 2007), proteolytic enzymes (MAURER, 2001) and secondary metabolites with antioxidant and biological activities of great value for the pharmaceutical, cosmetic and food industry (HARVEY, 2000;MANETTI;DELAPORTE;LAVERDE JUNIOR, 2009), besides its great ornamental potential (CHAN, 2006;COPPENS D'EECKENBRUGGE;DUVAL, 2009;DUVAL et al, 2001;SANEWSKI, 2009;SOUZA et al, 2007;2009).…”
