A versatile approach to selective and inexpensive copper patterns using polyelectrolyte multilayer coatings

Precursor strategies for metallic nano- and micropatterns using soft lithography

“…The main advantage of this method is the direct deposition of the metal only on the activated region, without etching or posttreatment steps, making it a simple and cost-effective process. [65][66][67][68][69][70][71][72][73] In 2000, Kind et al successfully produced copper lines with lateral dimensions of 170 nm and 500 nm on substrates covered with titanium by printing a precursor based on bis(stearonitrile)palladium(II) dichloride. However, in the majority of cases, electroless plating is the method of choice because of its versatility, fast deposition rate, suitability for scaling-up and only basic equipment is needed.…”

Selective Metal Pattern Fabrication Through Micro-Contact or Ink-Jet Printing and Electroless Plating onto Polymer Surfaces Chemically Modified by Plasma Treatments

“…In that work, the PTFE surface was first Ar plasma pre-treated, then stamped by mCP using a N-[3(trimethoxysilyl)-propyl]diethylenetriamine (TMS) coupling agent, and subsequently activated in an acidic PdCl 2 solution. More recently, Hendricks and co-workers [13,14] described a versatile metal (Cu or Ni) patterning method combining the use of polyelectrolyte multilayer (PEM) coatings, mCP, and ELD. The PEM coatings were obtained by dipping the substrates [glasses, poly(styrene) microscope slides and flexible polyester transparency films] successively into solutions of positively charged poly(diallyldimethylammonium) chloride (PDAC) and negatively charged poly(styrene) sulfonate, the final layer of the outer surface being made of PDAC.…”

“…For this purpose, commercial piezoelectric desktop printers controlled by conventional computer software can be used to deliver picoliter volumes of the ''ink'' to be deposited. Both techniques (mCP and IJP) combined with electroless plating have been shown nowadays to be able to provide, under relatively environmentally friendly conditions, high speed patterning over large areas at the surface of various materials, including that of polymer substrates [11][12][13][14][15][16][17][18][19][20][21][22].…”

Nano-deposition on 3-D open-cell aluminum foam materials for improved energy absorption capacity

“…Self-assembled nano-composites or nano-coatings have been introduced to provide materials with multifunctional properties or to reinforce substrates for enhancements not only at the microscale but also at the macro-scale level [20][21][22][23][24][25][26][27][28][29][30][31][32]. Hybrid nanocrystalline Ni/Al metal foams were fabricated and identified as composite material system with reinforced mechanical properties [33,34].…”
