Description
基板ベース物質として、ゼラチンを用いた。ゼラチンを基にした電子素子用分解性基板は、乾燥したアルゴン(Ar)雰囲気のグローブボックス(glove box)内で、HFIP 20mLに0.6~1g(3-5%w/v)の豚(porcine)から抽出したゼラチンと、可塑剤であるグリセロール(glycerol)0.3~1g(1.5-5% w/v)を添加して、高分子溶液を製造した。分解性気泡生成物質は、粉砕した有機酸(クエン酸)と炭酸水素塩(炭酸水素ナトリウム)を、0.3~1.2g(1.5~6% w/v)入れて混合撹拌し(分子比、有機酸:炭酸水素塩=1:1~1:3)、PDMS(ポリ(ジメチルシロキサン))鋳造型に溶液を満たして、24時間の間、乾燥後、乾燥機で更に24時間を乾燥して、電子素子用分解性基板を製造した。厚さは、ゼラチンに対する分解性気泡生成物質の割合によって、50μm乃至200μmとした。ここで、電子素子用分解性基板は、ゼラチンと分解性気泡生成物質が10:3乃至1:2の重量比を有する。
また、他の例として、基板ベース物質として、PLGAを用いた。PLGAに基づく電子素子用分解性基板は、前記ゼラチンと同一の条件で製造し、アセトン20mLに、PLGA(ラクチド(Lactide):グリコリド(Glycolide)=50:50、65:35)1~2g(5-10% w/v)を溶解して、高分子溶液を形成する。分解性気泡生成物質は、分子比(1:1~1:3)の粉砕した有機酸と炭酸水素塩0.5~2g(2.5.~10% w/v)を入れて混合し、PDMS鋳造型に入れ、前記と同様な方法で乾燥して、電子素子用分解性基板を製造した。ここで、電子素子用分解性基板は、PLGAと分解性気泡生成物質が、4:1乃至1:2の重量比を有する。
