Polymer-based far-infrared radiation (FIR) composite materials are receiving increasing attention due to their significant influence on bioactivity. This study reports the processing of FIR composite films based on a polymer matrix and FIR radiation ceramic powders, as well as the characterization of the FIR composites. Field-emission scanning electron microscopy (SEM) and laser particle size analysis were employed to analyze the characteristic of the ceramic powders. The average size, dispersity, and specific surface area of the ceramic powders were 2602 nm, 0.97961, and 0.76 m/g, respectively. The results show that the FIR ceramic powders used in the composite films had excellent far-infrared emissive performance. Moreover, by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TG), it was indicated that the thermal performance and mechanical properties of the composite films were significantly influenced ( < 0.05) by the addition of the FIR ceramic powders. Specifically, the elongation at break decreased from 333 mm to 201 mm with the increase in FIR ceramic powders. Meanwhile, the contact angle and light transmittance were also changed by the addition of the FIR ceramic powders. Furthermore, the two different processing methods had great influence on the properties of the composite films. Moreover, the composite blown films with 1.5% FIR ceramic powders showed the highest far-infrared emissivity, which was 0.924.
基于聚合物的远红外辐射（FIR）复合材料因其对生物活性的显著影响而受到越来越多的关注。本研究报道了基于聚合物基体和FIR辐射陶瓷粉末的FIR复合薄膜的制备过程以及FIR复合材料的表征。采用场发射扫描电子显微镜（SEM）和激光粒度分析来分析陶瓷粉末的特性。陶瓷粉末的平均尺寸、分散度和比表面积分别为2602 nm、0.97961和0.76 m/g。结果表明，复合薄膜中使用的FIR陶瓷粉末具有优异的远红外发射性能。此外，通过差示扫描量热法（DSC）和热重分析（TG）表明，FIR陶瓷粉末的添加对复合薄膜的热性能和力学性能有显著影响（<0.05）。具体而言，随着FIR陶瓷粉末含量的增加，断裂伸长率从333 mm降至201 mm。同时，FIR陶瓷粉末的添加也改变了接触角和透光率。此外，两种不同的加工方法对复合薄膜的性能有很大影响。此外，含有1.5% FIR陶瓷粉末的复合吹塑薄膜具有最高的远红外发射率，为0.924。
