Abstract Dioctyl terephthalate is of great interest as a replacement for the phthalate plasticizers such as dioctyl phthalate and diisononyl phthalate due to its orthophthalate-free and non-carcinogenic properties. This study focused on the production, characterization and optimization of the quality characteristics of its film properties, such as the mechanical, hydrophilic and thermal properties of dioctyl terephthalate-blended polyvinyl alcohol composites modified with graphene oxide and silver nanoparticles using TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) based Taguchi Method. Dioctyl terephthalate has brought remarkable features, such as high elastic modulus, and hydrophilic and thermal stability to the polyvinyl alcohol matrix. The optimum Dioctyl terephthalate -blended polyvinyl alcohol films have a 2.26 times lower contact angle and a 13.41 times higher elastic modulus than the reference polyvinyl alcohol film. Dioctyl terephthalate should be preferentially used to manufacture more durable and hydrophilic composite films such as fibers, disposable underpad or industrial swab, instead of toxic phthalate plasticizers.

掺入氧化石墨烯和银纳米颗粒的新型对苯二甲酸二辛酯混合聚乙烯醇复合薄膜的制备和表征

摘要 对苯二甲酸二辛酯作为邻苯二甲酸二辛酯和邻苯二甲酸二异壬酯等邻苯二甲酸酯增塑剂的替代品，由于其不含邻苯二甲酸酯且无致癌性而备受关注。本研究的重点是使用 TOPSIS（订购偏好技术）对氧化石墨烯和银纳米颗粒改性的对苯二甲酸二辛酯混合聚乙烯醇复合材料的机械、亲水和热性能等薄膜特性的质量特性进行生产、表征和优化。通过与理想解决方案的相似性）基于田口方法。对苯二甲酸二辛酯为聚乙烯醇基体带来了高弹性模量、亲水性和热稳定性等显着特点。最佳的对苯二甲酸二辛酯共混聚乙烯醇薄膜具有 2。与参考聚乙烯醇薄膜相比，接触角低 26 倍，弹性模量高 13.41 倍。对苯二甲酸二辛酯应优先用于制造更耐用和亲水的复合薄膜，如纤维、一次性底垫或工业棉签，而不是有毒的邻苯二甲酸酯增塑剂。
