项目摘要

令和４年度には、赤外線誘起発熱に伴って変形するナノカーボン複合材料を試作するため、LCST（下限臨界溶液温度）型の温度応答性を示す材料であるポリ(N-イソプロピル)アクリルアミド（PNIPAM）ハイドロゲルとポリエチレングリコールジアクリレート（PEGDA）ゲルからなる積層材料を作製し、赤外線照射に伴う屈曲変形を観察した。この積層材料では、温度上昇・低下に伴う両層の膨潤率変化の差によって変形が引き起こされると考えられており、PNIPAM層への還元型酸化グラフェンの添加により赤外線照射・発熱による屈曲変形が可能であることが知られている。本研究では、光熱変換を担うナノカーボンとしてカーボンナノチューブ（CNT）を用い、赤外線照射に伴う温度上昇および変形挙動に対するCNT添加量の影響を調べた。NIPAM、PEGDAおよび多層カーボンナノチューブ（MWCNT）分散液から作製した種々のMWCNT添加率の積層材料に赤外光(波長810 nm)を照射し、温度変化および屈曲変位を測定した。MWCNT添加率が低い試料では、赤外線照射時の到達温度が比較的低いが、重量の減少と屈曲変形が同時に観察された。一方、 MWCNT添加率が高い試料ではPNIPAM のLCST付近まで温度が上昇し、更なる重量減少を伴わずに屈曲変形することが観察された。これらのことは、 MWCNT添加率の低い試料では主に水分の蒸発に伴って変形する一方、CNT 添加率の高い試料では PNIPAMの温度応答性に基づく両層での水分移動により変形することを示唆していると考えている。

In terms of temperature, temperature The purpose of this study is to increase the amount of CNT in the presence of high temperature radiation (CNT). In this study, the light source and light source are used to determine the effect of radiation on the temperature of the device. The dispersion solution of NIPAM and PEGDA was used to determine the addition rate of MWCNT and the active material was irradiated with infrared light (wavelength 810 nm), and the buckling position was measured by temperature curing. The addition rate of MWCNT is low, the temperature is lower than the temperature, the weight is less, and the buckling shape is observed at the same time. On the one hand, the addition rate of MWCNT is high, PNIPAM, LCST, temperature, temperature, weight, buckling, buckling, temperature, temperature and temperature. In terms of temperature, MWCNT addition rate, temperature response, temperature response, moisture transfer, temperature response, temperature response, temperature response
