Abstract
Description
基材11として絹布を用意し、PEDOTの単量体溶液(Heraeus CleviosM−V2)と、酸化剤及びドーパントであるpTS(Heraeus CleviosC−B40V2)と、溶媒であるエタノールとの混合溶液を塗布し、1時間保持してPEDOTの単量体を重合させた。pTSとPEDOTの単量体との割合は、体積比で、40:2とし、エタノールと酸化剤の合計に対する酸化剤の割合は、30質量%とした。また、PEDOTの単量体を重合させる際に、実施例1−1では55℃に加熱し、実施例1−2では加熱せず室温で行った。これにより導電性高分子導電体10を得た。
pTSとPEDOTの単量体との割合を変化させたことを除き、他は実施例1−2と同様にして導電性高分子導電体10を作製した。pTSとPEDOTの単量体との割合は、体積比で、実施例2−1は40:1、実施例2−1は40:2、実施例2−3は40:3、実施例2−4は40:4、実施例2−5は40:5とした。各実施例について、洗濯を1回から10回行い、洗濯前(すなわち洗濯0回)及び各洗濯後毎に、実施例1−2と同様にして表面抵抗を測定し、洗濯による抵抗の変化を調べた。得られた結果を図7に示す。
実施例3−1〜3−5では、基材11をポリエステル系布に変えたことを除き、他は実施例2−1〜2−5と同様にして導電性高分子導電体10を作製した。その際、pTSとPEDOTの単量体との割合は、実施例2−1〜2−5と同様に変化させた。また、実施例4−1〜4−3では、基材11を綿布とし、布の種類を各実施例で変えたことを除き、他は実施例2−2と同様にして導電性高分子導電体10を作製した。布の種類は、実施例4−1ではオックスフォード、実施例4−2ではツイル、実施例4−3ではデニムとした。pTSとPEDOTの単量体との割合は、体積比で、40:2とした。各実施例について、実施例2−1〜2−5と同様にして表面抵抗を測定し、洗濯による抵抗の変化を調べた。得られた結果を図8及び図9に示す。
実施例5−1〜5−5でpTSとPEDOTの単量体との割合を変化させ、更に、各実施例において、エタノールと酸化剤の合計に対する酸化剤の割合を変化させたこと除き、他は実施例1−2と同様にして導電性高分子導電体10を作製し、同様にして表面抵抗を測定すると共に、電気伝導度を算出した。その際、pTSとPEDOTの単量体との割合は、実施例5−1〜5−5で実施例2−1〜2−5と同様に変化させ、エタノールと酸化剤の合計に対する酸化剤の割合は、各実施例において、60質量%、30質量%、20質量%、15質量%、12質量%と変化させた。得られた結果を図10及び図11に示す。図10及び図11では、各実施例において、左から順に60質量%、30質量%、20質量%、15質量%、12質量%の結果を並べて示している。図10は抵抗値の結果、図11は電気伝導度の結果である。
また、従来は、主にAg金属をコーティングしたものも一般的に利用されているが、生体への悪影響が懸念されている。さらに、湿気、汗で電極が酸化され、性能劣化を起こす問題もあった。すなわち、長時間使い続けても生体に悪影響を与えない電極であることが望まれている。
本願発明によれば、例えば、市販のアンダーウェアの表面に導電性高分子の単量体、酸化剤、及び、溶媒であるエタノールを含む混合溶液を塗布して化学反応によって重合させ、導電性の機能をアンダーウェアに持たせることができる。その電極は生体に強く押し付けることはなく測定でき、従来の製品より低コストでアンダーウェアを製作することができ、生体情報を検出できる。ウェアの価格が安くなればヘルスケアや介護用の支援ロボット、作業用の支援ロボット、フィットネス、作業服等に広く応用することができる。
