Magnetic Remote Activation of Shape Recovery in Nanocomposites Based on Tung Oil and Styrene

Abstract: The activation of unconstrained shape recovery in bio‐based polymeric nanocomposites is successfully achieved using magnetic nanoparticle heating. The materials investigated in this work present several distinct physical and chemical characteristics worth pointing out: they can be deformed and the original shape can be recovered by remotely heating the samples above their switching temperature, which is determined by their glass transition temperatures. Also, their chemical composition is largely based on biom… Show more

“…The X-ray diffraction analyses were carried out to identify the crystalline peaks related to geopolymers’ formation with magnetic particles and the modification of the magnetic particles with SiO 2 . Thus, it was possible to identify peaks at 17° angles in the composites, 27.5°, 37°, 41°, and 47° referring to the Sodalite phase and the 24° and 30° peaks of quartz, these being the main formation phases of geopolymers [ 31 ]; furthermore, the peaks centered at 35° and 51° identified the presence of magnetite inserted in the geopolymer matrix shows the Figure 3 A(a) [ 32 , 33 , 34 , 35 , 36 ].…”

“…In one of our previous works using MNP in a thermoset matrix, we found that MNP formed isolated fractal structures at 1.5 wt%, but higher concentrations lead to a continuous network of MNP through the sample. [ 21 ]…”

“…[ 15–18 ] In particular, MNPs have been considered widely to generate materials with magnetic or superparamagnetic properties, that can be used in medical applications, sensors, magnetic filters, or incorporated in materials to be applied in anechoic chambers or as antistatic coatings, etc. [ 19–22 ]…”

“…[1][2][3][4][5][6][7][8][9] There are several types of SMP materials, and they can be divided into thermally, electrically, photo, magnetically, and chemically actuated SMPs. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] At present, most SMPs are thermally actuated, and they are heated to a shape memory transition temperature T trans (T trans is the shape memory transition temperature, which is the glass transition temperature or melting transition temperature). Then, the temporary shape of the SMP is fixed by maintaining the external force and reducing the temperature to below T trans .…”
