Abstract

Turkey has the largest colemanite reserves in the world, mainly used in glass and boric acid productions. In order to broaden the current applications of colemanite, it was previously transformed to apatite by a novel method within the same working group of the authors. Natural bone is an organic–inorganic composite where inorganic apatite crystals are accumulated on organic collagen fibers. With inspiration from nature, one further step was taken as an addition to the previous study: apatite, produced from colemanite, and Polyvinyl alcohol (PVA) were mixed with different weight ratios, and, then dried by a spray dryer to investigate the effect of PVA content on the composite structure and to see the effect of using a spray dryer on the morphology of the composites. The weight ratios of Apatite-PVA were maintained as 3:7, 5:5 and 8:2. Samples in each step were analyzed by XRD, FTIR, and SEM. It showed that spray dried Apatite-PVA composites were successfully synthesized and could be potential biomaterials. Using a spray dryer and the manipulation of the weight ratios of the Apatite-PVA were effective ways to tailor the particle size of the powder and the morphology of the particles, which could be beneficial for their biomedical usage.

聚乙烯醇(PVA)重量比对喷雾干燥磷灰石-PVA复合材料的影响

土耳其拥有世界上最大的colemanite储量，主要用于玻璃和硼酸生产。为了拓宽目前colemanite的应用范围，作者在同一工作组内采用一种新方法将其转化为磷灰石。天然骨是一种有机-无机复合材料，无机磷灰石晶体积聚在有机胶原纤维上。在大自然的启发下，我们在之前的研究基础上又进行了进一步的研究:将由colemanite生产的磷灰石与聚乙烯醇(PVA)按不同的重量比混合，然后用喷雾干燥机进行干燥，研究PVA含量对复合材料结构的影响，并观察喷雾干燥机对复合材料形貌的影响。磷灰石-聚乙烯醇的质量比维持在3:7、5:5和8:2。采用XRD、FTIR、SEM对各步骤样品进行分析。结果表明，喷雾干燥磷灰石-聚乙烯醇复合材料制备成功，是一种有潜力的生物材料。使用喷雾干燥机和控制磷灰石-聚乙烯醇的重量比是调整粉末粒度和颗粒形态的有效方法，这可能有利于其生物医学用途。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
