So it is urgent to broaden the application of PLA materials and remedy their imperfects in the area of biomedicine by modification[1-3].
Experimental Materials.
When contacting with blood, materials would adhere platelet more or less, large number of platelet adhesion and badly distortion would lead to platelet aggregation, then promote platelet factor release, coacervation and coagulation factor activation, at last form thrombus.

Flexible PU foam not only an excellence material in packing industries, the viscoelastic properties of these materials makes it among desirable material for cushioning due to its unique ability to redistribute body weight and restrict the levels of pressure,provide comfortable support and ease pain by prolonged stiffness [3].
The cost of producing composite comprising organic products such as lignocellulosic materials as the reinforcing filler and thermoplastic polymer as the matrix polymer is quite low.
Besides, these materials can easily be obtained from waste products and have a minimal effect on the environment [5].

Plasma-inducing grafting polymerization [6] and ultroviolet irradiation are attractive ways of modifying the surface chemistry and morphology of polymeric materials.
Materials and Methods PET films were supplied by 3M company, America.
It is suggested that the significantly lower interface free energy between materials and blood or plasma proteins give them good blood compatibility [9].
The other is that lower interface free energy between materials and biological substances exhibits good blood compatibility.

Introduction Over the years considerable research has been carried out in the use of sound waves to detect various defects that occur in materials.
Sound waves in materials and over surfaces There are only two types of sound wave that can propagate within the bulk mass of a homogeneous unbounded material, these are known as P-waves and S-waves.
In hetrogeneous materials the energy of the wave can be converted to different wave propagation modes, at the material boundaries compressional waves or shear waves can be formed.
• Over extensive, homogeneous materials, they are non-dispersive.

Materials were dried at 70[℃] for 1 [hour].
After an hour, the materials were placed in the bottle (size; 31.9[cm] ×48.5[cm] ×87.0[cm]) and 20[g] of sliced garlic were placed on the top of the materials. 0.5[ml] of air in the bottles was taken at 0 hour and 72 hours respectively.
Evaluation of lightness (L*) changes for both materials treatment was significantly higher than the baseline result and differ each other by 1 point.

Experimental Procedure The materials used in this study include eggshell and silica, both sourced from the Abuja metropolis, Nigeria.
The resulting weight loss as temperature increased was tracked to understand the decomposition behavior and thermal resistance of the materials.
From this result, both materials possess mesoporous characteristics, with pore diameters within the 2–50 nm range.
