Precipitating, is washed with deionized 3~5 times, is placed in 100~120 DEG C of baking oven and dries to constant weight, is cooled to room temperature, and grinds
Up to modified medical stone powder；
(2) according to parts by weight, weigh respectively 20~33 parts of polylactic acid, 1~10 part of polycaprolactone, 40~56 parts of chloroforms,
20~26 parts of modified medical stone powders, polylactic acid, polycaprolactone, chloroform are uniformly mixed, and stirring in water bath processing obtains mixed liquor
C is added modified medical stone powder, continues 6~7h of stirring, standing and defoaming is to get polydactyl acid；
(3) according to parts by weight, 30~60 parts of polydactyl acids, 4~10 parts of polyethylene glycol, 10~16 parts of Nanowires are weighed respectively
Dimension element, 20~40 parts of chloroforms, polydactyl acid and polyethylene glycol are mixed, and after 5~10min of ultrasound and are stirred 1~3h, are obtained
Precursor solution mixes nano-cellulose and chloroform, stirs 2~3h, obtains blended liquid, blended liquid is added to presoma
In solution, stir process obtains matrix, and matrix is scraped film process, takes off film after natural drying, and dries extremely in 40~50 DEG C of baking ovens
Constant weight is to get polylactic acid film.
It is 300~350W that sonic oscillation described in step (1), which is in power, 4~5h of sonic oscillation under room temperature.
Medical stone powder described in step (1) crosses 400~500 meshes.
The processing of stirring in water bath described in step (2) is that low whipping speed is 60~100r/min, and temperature is at 40~50 DEG C
30~50min of stirring in water bath.
Stir process described in step (3) is that low whipping speed is 20~30min of stirring under 1000~2000r/min.
It with speed is 10mm/s knifing on a glass that film process is scraped described in step (3), which is by matrix, with a thickness of 50~
60um。
The present invention is compared with other methods, and advantageous effects are:
(1) present invention restores silver using organic reducing method and is attached on medical stone powder, is made and carries silver-colored medical stone powder, carries silver-colored wheat
Meal mountain flour has stronger absorption property and antibacterial action, not only can effectively adsorb organic matter in air and part is inorganic miscellaneous
Matter, can also effectively inhibit the growth and breeding of bacterium, and silver can be in conjunction with phosphide and sulfide on bacterial cell membrane, thus broken
Bad cell permeability of the membrane；Into cell membrane nano silver can in intracellular protein and DNA sulfide or phosphide it is anti-
It answers, the function of desmoenzyme and the duplication transcription of DNA is blocked, so that the polylactic acid film of preparation has good antibacterial effect；
(2) present invention carries out polylactic acid by the way that polyethylene glycol is added using solution intercalation method by polylactic acid intercalation medical stone powder
Plasticization and modification, is prepared for the polylactic acid film with good flexibility, hot property and mechanical property, polylactic acid have it is nontoxic,
Easy processing, heat stable property also have excellent biocompatibility and biodegradable properties, in polylactic acid molecule structure,
The hydrolysis of ester bond is one of the major way of polylactic acid degradation, since ester bond is sensitive to alkali, in alkaline solution, and polylactic acid
Hydrolysis of ester group generate carboxylate, be conducive to hydrolysis to positive reaction direction carry out, the polylactic acid film of preparation is mainly water
Ester group cleavage caused by solving, the acid that degradation process generates may have catalytic action to degradation.
