Here we report an unconventional approach for the single-step synthesis of monolithically integrated electronic devices based on multidimensional carbon structures. Integrated arrays field-effect transistors and sensors composed nanotube channels graphitic electrodes interconnects were formed directly from synthesis. These fully integrated, all-carbon are highly flexible can be transferred onto both planar nonplanar substrates, including papers, clothes, fingernails. Furthermore, sensor...
Although epoxy-based composites that consist of inorganic fillers and matrixes are widely used in "conventional" electronic packaging applications due to their excellent insulation robust properties, they limit uses "advanced packaging" which requires enhanced thermal conductivity. However, conventional curing methods for fabrication do not fulfill sufficient Herein, we apply photo-induced strategy fabricating alumina-incorporated epoxy-siloxane sol-gel derived siloxane matrix bimodal sized...
Organic-inorganic nanohybrid materials were successfully fabricated from organically modified colloidal-silica nanoparticles synthesized through the sol-gel process and using acryl resin. The exhibited simple solution-processible film formation high transmittance of above 90% in visible wavelength regions. used for fabrication various patterns photolithography. We could simply fabricate photopatterns easily control surface structures by changing content nanoparticles. Also, thermal...
Organically modified germanosilicate (ORMOGSIL) glasses prepared by a sol‐gel method showed large refractive index change on ultraviolet exposure. The photoinduced in the ORMOGSIL is mainly due to structural densification caused irradiation. shifts frequency of Raman bands measured at room temperature reveal reduction average intertetrahedral bonding angle θ glasses. Surface relief patterns were directly inscribed
Solventless silica-acryl hybrid materials composed of organically modified silica nanoparticles and acryl monomers were fabricated using a simple sol-gel process solvent evaporation. The homogeneously dispersed can be formed into films through solution-coating UV curing. exhibited good photocurability with -90% conversion upon exposure high transmittance above 95% in the visible wavelength region regardless nanoparticle content. In particular, increased mechanical hardness thermal stability...
The ZrO2-sol was prepared with zirconium acetate and water below 60°C followed by the modification 0, 0.5 5 mol of methyltrimethoxysilane(MTMS) via sol-gel method. epoxy system consisted 1,1,1-(triglycidyl-oxyphenyl) methane, (3-4-epoxycyclohexane) methyl-3-4-epoxycyclohexyl carboxylate, methyl-2,3-norbornanedicarboxylic anhybride, ethyl triphenyl phosphonium iodide N,N-dimethylacetamide (DMAc). MTMS-modified ZrO2-sols were mixed to be solid contents 90 : 10 weight percentages. ZrO2...
Hybrid materials composed of organically modified silica nanoparticles and oligosiloxanes exhibited homogeneous dispersion without any phase separation or aggregation good solution processability. These hybrid solubility photoinitiator high transmittance above 90% in visible wavelength ranges. In particular, the showed photocurability, with degrees conversion under UV exposure 90%. With photosensitivity, were used for direct photopatterning developing process photomask method. The various...
