Process for obtaining uniform dispersions of aggregates of graphenic nanofilaments in water, said process comprising the following stages: a) arranging aggregates of graphenic nanofilaments (1.1) wherein the structure of the graphenic nanofilaments comprises a continuous ribbon with five or fewer graphenic layers, spirally wound about and along the main axis s of each of said graphenic nanofilaments (1.1), b) adding the aggregates of graphenic nanofilaments (1.1) to an amount of water in order to obtain a first mixture of aggregates of graphenic nanofilaments (1.1) and water wherein the percentage by weight of the aggregates of graphenic nanofilaments (1.1) is from 1% to 5% with respect to the total weight of said first mixture, c) stirring the first mixture of aggregates of graphenic nanofilaments (1.1) and water, which comprises recirculation of the water by stirring in order to wet said aggregates of graphenic nanofilaments (1.1) and obtain a second mixture of aggregates of graphenic nanofilaments (1.1) and water, so that the size of the aggregates of graphenic nanofilaments (1.1) responds to a distribution with a D09 percentile measured by the Dynamic Light Scattering method in an interval from 20 to 150 μm, d) partial deaggregation and stretching of aggregates of graphenic nanofilaments (1.1) of the second mixture of stage c) to obtain a first stable dispersion of modified aggregates of graphenic nanofilaments (1.1) and water, by a recirculation process of said water and transport of the aggregates of graphenic nanofilaments (1.1) of the second mixture, during which compression and shear loads are applied on the aggregates of graphenic nanofilaments (1.1) to modify them, increasing their outer surface in contact with the water by splitting them into smaller aggregates of graphenic nanofilaments (1.1), thereby increasing the number of aggregates of the second mixture, and by stretching them increasing their aspect ratio, such that the size of the modified aggregates of graphenic nanofilaments (1.1) responds to a distribution with a D09 percentile measured by the Dynamic Light Scattering method is in an interval from 10 to 110 μm, wherein the modified aggregates of graphenic nanofilaments (1.1) of the first stable dispersion of modified aggregates of graphenic nanofilaments (1.1) maintain a separation distance from one another constant in time, so that the percentage by weight of the modified aggregates of graphenic nanofilaments (1.1) is less than 10% with respect to the total weight of the first stable dispersion, and wherein the graphenic nanofilaments (1.1) maintain the structure of stage a), this is, a structure formed by a continuous ribbon with five or fewer graphenic layers, spirally wound about and along the main axis s of each of said graphenic nanofilaments (1.1). a) arranging aggregates of graphenic nanofilaments (1.1) wherein the structure of the graphenic nanofilaments comprises a continuous ribbon with five or fewer graphenic layers, spirally wound about and along the main axis s of each of said graphenic nanofilaments (1.1), b) adding the aggregates of graphenic nanofilaments (1.1) to an amount of water in order to obtain a first mixture of aggregates of graphenic nanofilaments (1.1) and water wherein the percentage by weight of the aggregates of graphenic nanofilaments (1.1) is from 1% to 5% with respect to the total weight of said first mixture, c) stirring the first mixture of aggregates of graphenic nanofilaments (1.1) and water, which comprises recirculation of the water by stirring in order to wet said aggregates of graphenic nanofilaments (1.1) and obtain a second mixture of aggregates of graphenic nanofilaments (1.1) and water, so that the size of the aggregates of graphenic nanofilaments (1.1) responds to a distribution with a D09 percentile measured by the Dynamic Light Scattering method in an interval from 20 to 150 μm, d) partial deaggregation and stretching of aggregates of graphenic nanofilaments (1.1) of the second mixture of stage c) to obtain a first stable dispersion of modified aggregates of graphenic nanofilaments (1.1) and water, by a recirculation process of said water and transport of the aggregates of graphenic nanofilaments (1.1) of the second mixture, during which compression and shear loads are applied on the aggregates of graphenic nanofilaments (1.1) to modify them, increasing their outer surface in contact with the water by splitting them into smaller aggregates of graphenic nanofilaments (1.1), thereby increasing the number of aggregates of the second mixture, and by stretching them increasing their aspect ratio, such that the size of the modified aggregates of graphenic nanofilaments (1.1) responds to a distribution with a D09 percentile measured by the Dynamic Light Scattering method is in an interval from 10 to 110 μm,
