Herein, novel polymer composite is fabricated by hybridizing poly (acrylic acid-co-methyl methacrylate) filaments with carboxymethyl cellulose, which efficiently reorients and strictly ties the fibrous chains to form polymeric units of plate-like morphology. This innovative hybrid polymer composite is analyzed using XRD, FT-IR, swelling and contact angle studies, DLS, AFM, and SEM. Removal efficiency of such polymer composite is scrutinized in colored wastewater treatment. Langmuir and pseudo-first-order kinetic models best describe safranine dye removal from wastewater, adopting exothermic adsorption progression with elevated capacity (~ 59.47 mg/g) and accelerated rate (~ 1.06 h). Such polymer composite exhibits persistent removal efficiency of ~ 90% within 10 min for five consecutive cycles. Hybrid polymer composite is good candidate platform for hosting Ag particles to heighten their antimicrobial activity against Escherichia coli and Staphylococcus aureus, far exceeding 75% reduction. Future studies on applicability of oxygen-rich polymer composites in wastewater treatment and disinfection are optimistic and extremely competent.

在此，通过将聚（丙烯酸 - 甲基丙烯酸甲酯）长丝与羧甲基纤维素杂交制备了新型聚合物复合材料，该材料能有效地使纤维链重新定向并紧密结合，形成板状形态的聚合物单元。使用X射线衍射（XRD）、傅里叶变换红外光谱（FT - IR）、溶胀和接触角研究、动态光散射（DLS）、原子力显微镜（AFM）和扫描电子显微镜（SEM）对这种创新的杂化聚合物复合材料进行了分析。在处理有色废水时，对这种聚合物复合材料的去除效率进行了仔细研究。朗缪尔模型和伪一级动力学模型能最好地描述从废水中去除番红花红染料的过程，其采用放热吸附过程，具有较高的吸附容量（约59.47 mg/g）和较快的吸附速率（约1.06 h）。这种聚合物复合材料在连续五个循环中，10分钟内的持续去除效率约为90%。杂化聚合物复合材料是承载银颗粒以增强其对大肠杆菌和金黄色葡萄球菌抗菌活性的良好候选平台，抗菌活性远超75%的降低率。未来关于富氧聚合物复合材料在废水处理和消毒方面适用性的研究前景乐观且极具潜力。
