Single walled carbon nanotubes are dispersed in water and attached to nylon fabric by a simple immersing-drying procedure, which is evidenced by data obtained using Raman spectroscopy, scanning electron microscopy and transmission electron microscopy. Thermalgravimetric analysis reveals the temperature at which the functionalized nylon fabric reaches its maximum weight loss rate increases about...

The effects of aeration through lid filters on the hyphal growth of Lentinula edodes (oak mushroom) in sawdust cultivation bags were investigated. The aeration treatment levels were traditional 27 mm hole cotton plugs, cotton balls and combinations of seven hole sizes × two hole positions (up and under) in the lids covering plastic bags containing 1.4 kg sawdust medium at 63% moisture that had ...

BACKGROUND AND AIMS Fabrics used in pollination bags may exclude pollen carried by biotic vectors, but have varying degrees of permeability to wind-borne pollen. The permeability of bags to wind-borne pollen may have important consequences in studies of pollination and reproductive biology. The permeability of four fabrics commonly used in the construction of pollination bags was examined. ME...

اهمیت روز افزون ترموپلاستیک nylon - 66 بدلیل کاربردهای گوناگون آن در صنایع پلیمری مختلف همچون الیاف مورد استفاده در تایرسازی، نساجی، پوشاک ، فرش و قطعات مهندسی می باشد. متاسفانه نایلون 66 در ایران تولید نشده است و تماما وارداتی است . تلاش به منظور تولید صنعتی این پلیمر مهندسی در ایران کاملا توجیه اقتصادی دارد. در این پژوه سینتیک پلیمریزاسیون نایلون 66 مفصلا مطالعه است ، و با حل معادلات دیفرانسی...

Polymer-inorganic core-shell nanofibers were produced by two-step approach; electrospinning and atomic layer deposition (ALD). First, nylon 6,6 (polymeric core) nanofibers were obtained by electrospinning, and then zinc oxide (ZnO) (inorganic shell) with precise thickness control was deposited onto electrospun nylon 6,6 nanofibers using ALD technique. The bead-free and uniform nylon 6,6 nanofib...

Toxic reaction to nylon following uncomplicated cataract surgery and vitrectomy has been documented in the literature. We report the case of an aniridic patient with a known adverse reaction to nylon in whom Prolene suture was used in Boston Keratoprosthesis type 1 (KPro) surgery. During follow-up the cornea was checked for signs of inflammation and toxic reaction; at last follow-up (18 months)...

A novel wood flour (WF)-filled composite based on the microfibrillar high-density polyethylene (HDPE) and Nylon-6 co-blend, in which both in situ formed Nylon-6 microfibrils and WF acted as reinforcing elements, was successfully developed using a two-step extrusion method. At the 30wt.% WF loading level, WF-filled composite based on the microfibrillized HDPE/Nylon-6 blend exhibited higher stren...

Tensile strength, Young's modulus, and toughness of electrospun nylon 6 non-woven fiber mats were improved by increasing individual nanofiber strength and fiber-fiber load sharing. Single-walled carbon nanotubes (CNTs) were used as reinforcement to increase the strength of the electrospun nylon 6 nanofibers. Young's modulus, tensile strength, and toughness of the nylon 6 non-woven fiber mats el...

Multiwalled carbon nanotube/nylon-6 nanocomposites (MWNT/nylon-6) were prepared by in situ polymerization, whereby functionalized MWNTs (F-MWNTs) and pristine MWNTs (P-MWNTs) were used as reinforcing materials. The F-MWNTs were functionalized by Friedel-Crafts acylation, which introduced aromatic amine (COC(6)H(4)-NH(2)) groups onto the side wall. Scanning electron microscopy (SEM) images obtai...
