Study on identification of plastic used for modern artwork

Abstract

Plastic has been widely used in modern artworks' materials due to its merits of process ability and mass production. In the country, value of plastic artifact is increasing but the field of plastic study is limited to industrial purpose. In this study, Identification methods of plastic were performed by SPME-GC/MS and pyrolysis-GC/MS using trace of samples. As a result of identification using SPME-GC/MS, aromatic compounds were identified from polyvinyl chloride. And alkane compounds were identified from polyethylene, and polypropylene. Aromatic compounds were identified from polystyrene, and diethylene glycol appeared in polyurethane based on polyester was identified from polyurethane. As a result of identification using pyrolysis-GC/MS, aliphatic alkenes compounds and phthalate(DEHP) were identified from polyvinyl chloride. Aliphatic alkenes compounds and phthalate(DIBP) were detected from polyethylene. 1-hexene, etc., were detected from polypropylene, aromatic compounds were identified from polystyrene, and methylene diphenyl diisocyanate which is polyurethane basic material was confirmed from polyurethane. This study suggested that non-destructive SPME and pyrolysis-GC/MS are useful to identify compounds particularly polystyrene and polyurethane. These two analytical methods were expected to be applied for identification of unidentified plastic artworks before conservation treatment.요 약: 플라스틱은 뛰어난 조형성 및 대량생산의 장점에 의하여 점차 현대 미술에 전반적으로 쓰이게

Study on Degradation Characteristic of Plastic Artwork for Conservation

“…현대예술작품 중 조각 작품의 경우 금속, 석재, 목재, 직 물 등 다양한 재질로 만들어진다. 이러한 천연 재료 외에도 뛰어난 작업성과 편리성 등의 장점에 따라 플라스틱을 조 각 작품의 재료로 이용하여 만들기도 한다 (Yu, 2014). 특 히 대형 플라스틱 작품은 전시 공간의 한계 등에 따라 옥외 에 설치하는 경우가 많으며, 이는 강한 햇빛, 높은 습도, 강 우 등 각종 열화 요인에 직접적으로 노출되어 열화가 진행 된다 (Song, 2009).…”
