Abstract

Polymer materials are used in a wide variety of fields such as automobiles, aerospace, energy, IT, and as well as simple household products. Despite high interest in the technological convergence of polymer materials for the sustaining progress, there have been only limited analyzes on the topic. This research attempted to analyze the types of convergence and the level of technology in the polymer materials field. For this purpose, we collected patent information from the PCT database and implemented a co-classification analysis. The research shows that Japan and Korea have more section-level convergence whilst US and Europe focus on field-level convergence. In terms of the quality measured by patent activity, patent competitiveness, and patent effect, Korean convergence technologies seem to be inferior to those of other countries.

고분자 소재는 생활용품 등은 물론 자동차, 우주항공, 에너지, IT산업 등 다양한 분야에 광범위하게 이용된다. 이러한 고분자 소재의 지속적 혁신을 위해 고분자 기술의 융합에 대한 관심은 높지만, 융합 동향에 대한 분석은 제한적이었다. 이에 본 논문에서는 특허 정보를 활용하여 주요 국가별 고분자 소재의 기술융합 형태와 기술수준을 분석하고자 하였다. 이를 위해 공개 등록 기준으로 2004년부터 2014년까지의 PCT를 수집하여 동시분류분석을 실시하였다. 연구 결과 일본과 한국은 기술의 분야를 넘어서는 대분류(섹션) 수준의 융합이 더 많은 반면, 미국과 유럽은 화학분야 내에서 중분류(Field) 수준의 융합이 더 많이 나타나고 있다. 그리고 특허활동력, 특허경쟁력, 특허영향력으로 살펴본 질적 측면에서는 한국 융합기술이 다른 나라에 비해 미흡한 것으로 나타났다.
