Problems solved by technology

However, traditional high-temperature sintering has two unavoidable disadvantages
First, high-temperature sintering consumes a lot of energy, and the sintering equipment is complicated
Second, high-temperature sintering is very destructive to the substrate. At present, many inkjet printed substrates cannot withstand high temperatures exceeding 150°C, resulting in unsatisfactory sintering effects.
[0011] The invention relates to an inkjet printing conductive ink that can be sintered at room temperature, and a room temperature sintering method thereof, which can solve the disadvantages caused by high temperature sintering
