This disclosure relates to tertiary amine solutions of metal precursors used for chemical vapor deposition or atomic layer deposition. The tertiary amine solutions have many advantages. They dissolve high concentrations of non-polar precursors without reacting with them. They do not supply impurities such as oxygen or halogens to the material being produced, nor do they etch or corrode them. Vaporization rates can be chosen so that the solute and solvent may be evaporated simultaneously, have high flash points, and low flammability. Small droplets may be formed easily which facilitate rapid evaporation without decomposition of he dissolved metal precursor to supply vapors for chemical vapor deposition or atomic layer deposition processes.

A method for depositing a metal layer includes a step of contacting a surface of an electrically conductive substrate with a vapor of a metal-containing compound for a first predetermined pulse time to form a modified surface on the electrically conductive substrate. The metal-containing compound is a metal diketonate or a structurally similar compound. The modified surface is contacted with a vapor of a reducing agent that is a hydrazine or a hydrazine derivative for a second predetermined pulse time to form a metal-containing film on the surface of the electrically conductive substrate.

A feedstock material for use in an additive manufacturing apparatus is prepared from a first material and a metal organic framework (MOF). The MOF comprises a plurality of nodes and a plurality of linkers, the plurality of linkers coupled to the plurality of nodes, thereby forming a framework. The MOF has a lower coefficient of thermal expansion than a coefficient of thermal expansion for the first material. As a result, the feedstock material has a reduced coefficient of thermal expansion as compared to the first material alone and thus exhibits low thermal expansion as its temperature is increased. The coefficient of thermal expansion for the MOF may be modified by using a different plurality of nodes and/or a different plurality of linkers, as well as by incorporating guest molecules or atoms into the framework of the MOF.
