The results showed that the blend degradation rate could be regulated by adjusting PLGA or PSTP content in the blends. For example, the weight loss of PGP/PLGA (70:30 by wt) film was 68.4% after 55 days, whereas that of PGP/PSTP (70:30 by wt) was 88.5% only after 12 days.
Methods ①Polyurethane(PU), p(3HB-co-3HH)(PHAs) and PHAs/PU polymer blend were smeared on slides to form film respectively. Then human fibroblast cells were seeded on the films and cultured for 3 days.
Then collagen was substituted by gel and to make gel blend solutions. Properties of both blend solutions, interaction among the three components and compatibility were studied and compared.
Third, temperature and time during blending has little effect on the properties of blend solution. The mass percent of the component is key factor to properties, compatibility, stability of blend solutions and interaction among components.
It was found that the presence of HDPE in the NR/BR/HDPE blend modified its thermo-plastielastomer properties and radiation inducedcross-linking was produced in the blended polymer structure.
We have optimized the concentration of the PVA, SA and CaCl_2 by the preparation ways of dropping polyvinyl alcohol and sodium alginate mixture solution into calcium chloride solution, and detected the drying and swelling rate of the blend hydrogel beads.
Comparing the growth of cell on porous and compact blend films,it was found that fibroblasts NIH3T3 could transfer into the interior of porous blend films.
A polyamic acid (PAA)/polyurethane (PU) blend with PU as the disperse phase was first prepared via in situ polymerization of pyromellitic dianhydride and 4,4-oxydianiline in PU solutions.
They came from Arctic-Tertiary, Paleo-tropical-Tertiary and Tethys-Tertiary florisitic elements, and the blend of the three elements with many genera of autochthonous origin.
The surface composition of the blend films was determined by Fourier transform infra-red spectroscopy coupled with a variable incidence angle attenuated total reflection accessory (ATR-FTIR).
The cells blend and produced crossing cells is the basic openrete of cells engineering This report showed the working institute and the structure of the cell blender of magnetism which was to utilize achieve alternate electric magnetism to damage the cells membrane and reachs the aim of the cells blend.When the cells sample was put in electric magnetism, Alternate electric magnetism could be changed into the complete cells blend. Magnetism blender is more controllable then viru...
In the study,we used the chitosan and PVAC to blend then cast thesolution on a glass plate,and the gelled layer was pressed by drying to give membrane.The purpose we prepared the compound membrane is not only to preserve thefunction of chitosan which can prevent bacterial infection and promote wound healing in medical,but also to overcome the weakness of the chitosan film in the phisicalmechanical performance.In the study,the prescription and technology of compound membrane were being prefected by ele...
The mechanical properties and γ-radiation effects of blended NR/BR/HDPE have been studied. It was found that the presence of HDPE in the NR/BR/HDPE blend modified its thermo-plastielastomer properties and radiation inducedcross-linking was produced in the blended polymer structure.
