This paper focuses on developing, fabricating, and characterizing composite polycaprolactone (PCL) membranes reinforced with titanium dioxide nanoparticles (NPs) elaborated by using two solvents; acetic acid and a mixture of chloroform and N,N-dimethylformamide (DMF). The resulting physical, chemical, and mechanical properties of the composite materials are studied by using experimental characterization techniques such as scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-Ray diffraction (XRD), Fourier-transform infrared (FTIR) analysis, contact angle (CA), uniaxial and biaxial tensile tests, and surface roughness measurements. Experimental results show that the composite material synthesized by sol-gel and chloroform-DMF has a better performance than the one obtained by using acetic acid as a solvent.
本文着重于开发、制造和表征用二氧化钛纳米颗粒(NPs)增强的复合聚己内酯(PCL)膜,该纳米颗粒通过使用两种溶剂(乙酸以及氯仿和N,N - 二甲基甲酰胺(DMF)的混合物)制备而成。通过使用扫描电子显微镜(SEM)、差示扫描量热法(DSC)、X射线衍射(XRD)、傅里叶变换红外(FTIR)分析、接触角(CA)、单轴和双轴拉伸试验以及表面粗糙度测量等实验表征技术,研究了复合材料所得的物理、化学和机械性能。实验结果表明,通过溶胶 - 凝胶法和氯仿 - DMF合成的复合材料比使用乙酸作为溶剂获得的复合材料具有更好的性能。
