摘要
人口老龄化是世界各国人口发展的必然趋势,我国是全世界人口老龄化程度比较高的国家之一。根据2019年的政府工作报告,到2050年,国内的老年人口将达到4.8亿人,占人口比重34.1%。青壮年的减少、婚育观的转变、人均寿命的提高都将加快我国进入深度老龄化社会。剧增的养老服务需要同紧张的医疗资源、短缺的护理人力之间的矛盾成为我国应对养老危机亟待解决的重大问题。综述了高分子新材料(聚乳酸、聚醚醚酮)的性能以及在人工器官、辅助药物、3D打印应用的研究进展,并对其未来在智慧养老方面的应用予以展望。
Population aging is an inevitable trend of population development in all countries in the world,China is one of the countries with a high degree of population aging in the world.According to the 2019 government work report,China’s elderly population will reach 480 million by 2050,accounting for 34.1 percent of the population.The decrease of young adults,the change of the concept of marriage and child-rearing,and the improvement of life expectancy will accelerate the entry of China into a deep aging society.The contradiction between the soaring demand of old-age service and the shortage of medical resources and nursing manpower has become a major problem to be solved urgently.The performance of the new polymer materials(PLA and PEEK)and their research progress in artificial organs,auxiliary drugs and 3D printing were reviewd.
