This work mainly depends on the assumption or hypothesis which exploits the tendency of natural rubber latex (NRL) to cross-link under irradiation in the presence of Alginate and CMC biopolymer and form (ALG/NRL and CMC/NRL) films containing polar/charged functional groups which offer them hydrophilicity, and consequently water absorption capacity. CMC/NRL and ALG/NRL (v/v) blend films prepared first by latex compounding followed by casting technique. The prepared ALG/NRL and CMC/NRL blend films characterized then, by various techniques such as IR, scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). Equilibrium swelling properties and gel percent GF% of prepared films also studied in details. GF% studies revealed that the GF% increased with increasing both NRL content and irradiation dose for both ALG/NRL and CMC/NRL. Thermal analysis shows the increased thermal stability of the irradiated samples due cross-linking effect of NRL. The improved gel content percentage obtained paved the way for the application of various films in the removal of toxic dyes such as acidic, direct, and basic dyes from waste water where in this study, the films exhibited high affinity toward basic blue dye.

γ辐照水溶性聚合物/天然胶乳共混物的制备、表征及应用
这项工作主要取决于利用天然橡胶胶乳 (NRL) 在海藻酸盐和 CMC 生物聚合物存在的情况下在辐照下交联的趋势的假设或假设,并形成含有极性/带电的 (ALG/NRL 和 CMC/NRL) 薄膜赋予它们亲水性并因此具有吸水能力的官能团。CMC/NRL 和 ALG/NRL (v/v) 共混薄膜首先通过胶乳复合制备,然后采用流延技术制备。所制备的 ALG/NRL 和 CMC/NRL 混合薄膜随后通过各种技术进行表征,例如 IR、扫描电子显微镜 (SEM) 和热重分析 (TGA)。还详细研究了所制备薄膜的平衡溶胀性能和凝胶百分比 GF%。GF% 研究表明,对于 ALG/NRL 和 CMC/NRL,GF% 随着 NRL 含量和辐照剂量的增加而增加。热分析表明,由于 NRL 的交联作用,辐照样品的热稳定性有所提高。凝胶含量百分比的提高为各种薄膜在去除废水中酸性、直接和碱性染料等有毒染料方面的应用铺平了道路,在本研究中,薄膜对碱性蓝色染料表现出高亲和力。
