Fig. 1 is the XRD spectrum of nanometer silver antimicrobial liquid, in 1g PVP, the glucose of the NaOH of 0.1mol/L, 0.2mol/L,
0.05mol/L AgNO3Solution, temperature be 140 DEG C at hydro-thermal reaction 6h preparation condition under.As shown in Figure 1, nano silver is in 2 θ
To there is 5 apparent absorption peaks at 38.10 °, 44.36 °, 64.47 °, 77.42 °, 81.30 °, the peak position of nano silver with
Data are consistent on JCPDS card 04-0783, correspond respectively to (111), (200), (220), (311), (222) of cubic system silver
Crystal face illustrates that sample is the elemental silver of centroid cubic crystal system;The curved diffraction peak is quite sharp, show sample crystallization performance compared with
It is good.Using the XRD spectrum of nanometer silver antimicrobial liquid, the average-size for calculating nano silver particles crystal grain by Scherrer formula is big
Small, the results are shown in Table 1.Table 1 the result shows that: crystallite dimension is calculated in 20nm or so in each crystal face.
The average grain size of 1 nano silver of table
Crystal face | 111 | 200 | 220 | 311 | 222 |
D(nm) | 20.02 | 21.43 | 20.02 | 19.34 | 20.67 |
Fig. 2 is in 1g PVP, the glucose of the NaOH of 0.1mol/L, 0.2mol/L, the AgNO of 0.05mol/L3Solution, temperature
Degree is the SEM figure that hydro-thermal reaction 6h prepares nanometer silver antimicrobial liquid at 140 DEG C.By Fig. 2, gained Nano silver grain is spherical shape, dispersion
Property is preferable, and grain diameter is uniform, and most of grain diameter is in 20nm or so.This sample place 30d after, the shape of nano-silver powder and
Partial size is there is no significantly changing, and also there is no significantly reuniting, what is obtained is still the good nano-silver powder of dispersion.It says
The nano-silver powder of bright preparation has very strong stability.
In the forming process of nano silver, add surfactant, make its be adsorbed on nano-Ag particles surface make them it
Between there are a kind of steric hindrance repulsion potential energy, potential barrier just will increase between such particle, to prevent particle agglomeration.In reaction temperature
Degree is 140 DEG C, the glucose of 0.2mol/L, 0.05mol/L AgNO3 solution, under conditions of the reaction time is 6h, when being with PEG
When dispersing agent, nano silver particles are reunited than more serious, and pattern is irregular, and particle is larger;When using PVA as dispersing agent constantly, particle
Reunite more serious, is generated almost without the particle of complete pattern;When using CTAB as dispersing agent, the spheroidal nanometer of class is formd
Silver, but grain diameter is larger while also having some particles reunion.It thus is seen that the presence of PVP is for spherical nano-silver pattern
It is formed with significant impact.
Using PVP as dispersing agent, the glucose of 0.2mol/L, 0.05mol/L AgNO3Solution, reaction time 6h, instead
Temperature is answered to have a significant impact the particle size and its pattern of nano silver.When temperature is lower, when being 50 DEG C, nucleation rate is relatively
Height, growth rate is relatively low, causes gained nano-Ag particles pattern imperfect and reunites seriously, while partial size is smaller, only
More than ten nanometers;When temperature is 100 DEG C, nano-Ag particles pattern tends towards stability, and only small part is reunited, and partial size is close to 20nm;Temperature
When degree is 140 DEG C, to disperse uniform nano silver particles, partial size is in 20nm or so;When temperature is 200 DEG C, it is fiercer to react,
The probability collided between particle increases, and causes to reunite than more serious, obtained nano-Ag particles partial size becomes larger and is distributed also not
It is uniformly 30-50nm.
It is 140 DEG C in reaction temperature, the glucose of 0.2mol/L, 0.05mol/LAgNO3Solution, reaction time 6h,
The concentration of NaOH has a significant impact to the formation of nano silver and its pattern, and the micro change of NaOH will cause nanoscale silver
Very big variation.When the concentration of NaOH is zero, reaction speed is very slow, nucleation rate be less than growth rate, nano silver nucleus to
Each crystal face growth, so that there are triangles for gained nano silver, hexagon is rodlike, the various patterns such as spherical shape;When the concentration of NaOH is
When 0.025mol/L, reaction speed is accelerated, and nucleation rate is accordingly also accelerated, and the silver particles of small particle can be along the biggish silver in part
Nucleating surface continued growth, the nano silver of formation are that particle diameter distribution is non-uniform discoid, and partial size is 100nm or so;Work as NaOH
Concentration be 0.05mol/L when, nucleation and growth carries out simultaneously, obtains the uniform ball shaped nano Argent grain of particle diameter distribution, partial size
Size is 50nm or so;When the concentration of NaOH is 0.1mol/L, atom has reached saturated concentration, nucleation speed in nucleation process
Rate is greater than growth rate, obtains the ball shaped nano Argent grain that partial size is smaller and is evenly distributed, and particle size is 20nm or so;Continue
Increase the concentration of NaOH when making its 0.15mol/L, due to nucleation rate too greatly and growth rate is too small that nano silver is caused to be reunited.
To sum up described, when the concentration of NaOH is 0.1mol/L, obtained spherical nano-silver particle distribution is uniform, and partial size is minimum.
It is 140 DEG C in reaction temperature, the glucose of 0.2mol/L, 0.05mol/L AgNO3When solution, the reaction time is to receiving
The formation of meter Yin has a great impact with pattern.As seen from the figure, reaction time 2h, nano silver particles are mostly small with nucleation stage
Graininess exists, and pattern is irregular, and partial size is mostly in more than ten rans;Reaction time is 4h, the pattern of spherical nano silver
More regular, particle diameter distribution is more uniform;Reaction time is 9h, and the silver particles of small particle continue along the biggish nucleating surface in part
Growth, thus the nano-Ag particles size formed is extremely uneven;React 18h after, little particle partial size increase, partial size redistribution compared with
Uniformly, it is possible thereby to infer during the reaction, with the continuity in reaction time, small particles tachyauxesis at big particle, with
Reaction time continues to extend to 18h or more, and particle can constantly increase, and finally obtained particle size will reach unanimity, this is
Due to joined dispersing agent PVP in experiment so that the little particle dispersion adhered in the larger particles of reunion, so that overall ruler
It is very little to tend to be more uniform again.The result shows that selecting the reaction time preferable for 6h.
PVP is a kind of common high molecular surfactant, white or off-white powder or particle, is with hygroscopicity
Runny powder, it is odorless, it is dissolved in water, alkali, acid and polar organic solvent, there is very strong dilatancy, it can be with multiclass substance network
It closes, is widely used in the preparation process of nano silver particles, surfactant PVP can play dispersion and protection in the reaction
Effect can inhibit the unconfined diffusion of nano silver particles and attachment in particle formation and growth course, control particle it is each to
Anisotropic growth, thus have larger impact for the formation and pattern of nano silver particles.In AgNO3Concentration is 0.05mol/L, NaOH
Concentration is 0.1mol/L, and reaction temperature is 140 DEG C, reaction time 6h, and when PVP is 0g, the silver particles of generation will occur
Reunite, the aggregate pattern of formation is irregular;0.6g PVP is added, the nanoscale silver of generation is not single, and particle diameter distribution is uneven
It is even;When 1.0gPVP is added, particle diameter distribution is uniform, is single dispersing ball nano silver;When 1.5g PVP is added, class ball is formed
Shape nano silver particles, particle size is smaller but particle diameter distribution is uneven.It can therefrom learn with PVP increasing concentrations, particle ruler
Very little smaller, dispersion effect is better, pattern closer to spherical, but with the increasing particle diameter distribution of concentration tend to less uniformly, because
This selection 1.0g PVP is appropriate.
The formation of silver-colored crystal includes two processes of nucleation and crystal growth, and nucleation process needs certain degree of supersaturation to overcome table
Face energy potential, nucleus growth process is then on the basis of nucleation early period, and the elemental silver newly restored is adsorbed on original nucleating surface
And grow up, the two processes are existed simultaneously in dropwise addition AgNO3In the overall process of solution, but early period based on being nucleated, stage with
Based on nucleus growth.When silver nitrate concentration is lower, if silver nitrate concentration is respectively 0.01mol/L, with the increasing of silver nitrate concentration
Greatly, the silver-colored nucleus of generation increases, and degree of super saturation is relatively low, and nucleus growth speed is slower, therefore the nano silver generated
The partial size of grain is smaller;As the increase of silver nitrate concentration, such as silver nitrate concentration are respectively 0.05mol/L growth rate with nucleation speed
When rate is identical, reach saturation state, the nano silver partial size generated at this time is minimum;As silver nitrate concentration further increases, satiety
Constantly increase with degree, maintains higher level so that the growth rate of silver-colored crystal is greater than nucleation rate, and therefore, generation is received
The partial size of rice Argent grain is larger.
The above described is only a preferred embodiment of the present invention, not making any form to technical solution of the present invention
On limitation.According to the technical essence of the invention any simple modification to the above embodiments, equivalent variations and repair
Decorations, in the range of still falling within technical solution of the present invention.
