Functional electrically conductive fabric with acceptable mechanical properties, which could be applied in electromagnetic shielding, was developed. Conductive cotton fabrics (cotton/PANI, cotton/Mn, cotton/Cu, and cotton/Co) were prepared by in situ chemical oxidative polymerization for (cotton/PANI) and pad dry curing method was used for nanometals application. The Nano size of the metals and polyaniline inclusion were proven through both Dynamic Liquid Scattering (DLS) and X-ray diffraction (XRD) which showed an increase in crystallite density in unit space and the nanoparticles ranged from 100–200 nm. The effect of gamma irradiation on different treated cotton fabrics was investigated. The mechanical properties against irradiation dose showed an improvement up to 40 kGy, for all treated fabrics. On the other hand, Young’s modulus for untreated cotton recorded the lowest value, while cotton/Co recorded the highest one. Moreover, both AC (Alternating Current) and DC (Direct current) conductivities values can be calculated. In DC conductivity cotton/PANI was found to be more conducive than the remainder of the treated fabric by surface metallization with transition metals; while in AC conductivity cotton/Mn was found to be more conducive than the rest of the treated samples. The conductivity value increases by increasing the gamma irradiation dose for cotton/PANI fabric. Also, g-factor values can be estimated from ESR signals and vary from 0.009 up to 0.059 for conductive cotton fabrics; whilst cotton/Mn fabric has six hyperfine splittings, indicating that it is a paramagnetic element.

导电棉织物的导电性和机械性能

开发了具有可接受的机械性能的功能性导电织物,该织物可用于电磁屏蔽。导电棉织物(棉/ PANI,棉/锰,棉/铜和棉/钴)通过原位化学氧化聚合制备(棉/ PANI),并采用干法固化法用于纳米金属。通过动态液体散射(DLS)和X射线衍射(XRD)证明了金属和聚苯胺夹杂物的纳米尺寸,它们显示出单位空间中微晶密度的增加,纳米颗粒的范围为100-200 nm。研究了γ射线辐照对不同处理的棉织物的影响。对于所有处理过的织物,抗辐照剂量的机械性能均提高了40 kGy。另一方面,未经处理的棉的杨氏模量最低,而棉/钴的杨氏模量最高。此外,可以计算交流电(AC)和直流电(DC)的电导率值。在直流电导率方面,发现棉/ PANI比其他经过处理的织物的过渡金属表面化处理更有利。而在交流电导率中,发现棉/锰比其余处理样品更有利。电导率值通过增加棉/ PANI织物的伽马辐照剂量来增加。同样,可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化。棉/锰织物具有六个超细分裂,表明它是顺磁性元素。此外,可以计算交流电(AC)和直流电(DC)的电导率值。在直流电导率方面,发现棉/ PANI比其他经过处理的织物的过渡金属表面化处理更有利。而在交流电导率中,发现棉/锰比其余处理样品更有利。电导率值通过增加棉/ PANI织物的伽马辐照剂量来增加。同样,可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化。棉/锰织物具有六个超细分裂,表明它是顺磁性元素。此外,可以计算交流电(AC)和直流电(DC)的电导率值。在直流电导率方面,发现棉/ PANI比其他经过处理的织物的过渡金属表面化处理更有利。而在交流电导率中,发现棉/锰比其余处理样品更有利。电导率值通过增加棉/ PANI织物的伽马辐照剂量来增加。同样,可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化。棉/锰织物具有六个超细分裂,表明它是顺磁性元素。在直流电导率方面,发现棉/ PANI比其他经过处理的织物的过渡金属表面化处理更有利。而在交流电导率中,发现棉/锰比其余处理样品更有利。电导率值通过增加棉/ PANI织物的伽马辐照剂量来增加。同样,可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化。棉/锰织物具有六个超细分裂,表明它是顺磁性元素。在直流电导率方面,发现棉/ PANI比其他经过处理的织物的过渡金属表面化处理更有利。而在交流电导率中,发现棉/锰比其余处理样品更有利。电导率值通过增加棉/ PANI织物的伽马辐照剂量来增加。同样,可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化。棉/锰织物具有六个超细分裂,表明它是顺磁性元素。可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化;棉/锰织物具有六个超细分裂,表明它是顺磁性元素。可以从ESR信号中估算出g因子值,导电棉织物的g因子值在0.009到0.059之间变化;棉/锰织物具有六个超细分裂,表明它是顺磁性元素。
