Preparation of β-cyclodextrin Modified Poly(d,l-lactic acid) and Its Blood Compatibility ZHU Jiu-jin1,2,a, QUAN Xue-jun1, WANG Yuan-liang2, and ZOU Shu-shu1 1School of Chemical and Biological Engineering, Chongqing University of Technology, Chongqing 400050, China 2Research Center of Bioinspired Materials Science and Engineering, College of Bioengineering, Chongqing University, Chongqing 400044, China azhujiujin@163.com Keywords: polylactic acid, β-cyclodextrin modified polylactic acid, platelet adhesion Abstract.
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.
Surface free energy and interface free energy of materials and biological substances [10] P.
