Ⅳ. Said planning research’s Results
- In patent and analysis of laminated Hanji and Hanji-type heating element, substituted process of manual manufacture of laminated Hanji paperboard is limited to part of Hanji doubling and processes related to systematic patents after Hanji doubling including impregnation, coating, drying, and etc. is registered; patent about manufacture of laminating direct-synthesis form between carbon-heating element and raw material of Hanji is also registered, but patent about laminating technique of carbon heating element and Hanji isn’t applied.
- Development of product utilizing characteristic of laminated Hanji, environment-friendly, thermokeeping, far IR emission, antibiotic, deodorization, and etc., is in steady pace and is predicted to have increased growth.
- B/C rates of value of applied and unapplied discount rate are all above criteria of economic analysis “1”; this project procured its economic feasibility.
ㅇDevelopment of manufacture and application technique of Nanofiber-based carbon heating element
- Confirmed that heating property analysis of Hanji heating element using carbon nanofibers and Hanji happens to be 80℃ and 109℃ when 10V(1.904W) and 15V(4.400W) was applied.
- Confirmed that 50mm×50mm Hanji paperboard heating element maintained 73℃(88Ω) for 5 hours.
- Our research confirmed Hanji paperboard heating element’s possibility and high potential; still needs in-depth research on manufacturing bigger Hanji paperboard heating element than that of 50mm×50mm for our objective, applying laminated replaceable heating element into traditional Hanok.
ㅇDevelopment of manufacture technique of pitch-based high-conductive carbon sheets
- After observing morphology of carbon sheets relative to content of carbonblack, confirmed that, in surface of macromolecule combined substance between carbon fibers and its surface of carbon sheets, carbon black was dispersed uniformly, but requires intense research on drawback about cohesion symptom between filers when carbonblack content reached above 8wt%.
- SEM photograph of carbonblack added carbon sheets:
Confirmed that electrical property of carbon sheets manufactured depending on types of carbon fillers enhanced by adding carbon fillers; uniform dispersion of phenolic resin, combined material between carbon fibers, added carbonblack and carbon nanotube enhanced the electrical property. Thus, the enhancement could be strengthened when dispersion quality of carbon fillers improves.
ㅇDevelopment of conductive material coating technique/ transparent nanofiber heating element application technique
- Length of Ag NWs, synthesis of ethylene glycol as deoxidating agent and AgNo₃, is 25±5 ㎛ and diameter of 32±5 ㎚.
- Measured side-resistance(<15 ohm/sq) and transmittance(>80%) of synthesized Ag NWs coated in transparent PET substrate and dried (80~110℃, 10~60min). (electrical, optical properties)
ㅇDevelopment of laminating technique of Hanji and carbon material as heating element.
- Used PET in order to combine wet Hanji, synthesis of medium, adhesive material for combining CNF, and CNF in high-temperature drying process.
- Manufactured sheets with synthesis with various mixing ratio of paper mulberry pulp and synthesis of CNF and PET in 8:2 mixing ratio. Relatively elongate fiber, carbon nanofibers and paper mulberry fiber, used PEO(Polyethylen Oxide) for uniformly dispersing purpose; similar material property was measured in laminated Hanji paperboard heating element.
- Showing low mechanical property even though low-melting PET was added to CNF which has no self-binding force, the mechanical property was enhanced relative to paper mulberry pulp content; requires substance that could overcome decrease of mechanical property and development of manufacturing technique for stabilized dispersion.
